Hardware description

The product provides 1200 dot-per-inch (dpi) printing. The flatbed scanner scans at 600 pixels-per-inch (ppi) with 24-bits per pixel (bpp) and most models contain an automatic document feeder (ADF) that holds up to 50 pages. On the HP LaserJet 3330mfp, the formatter and LIU provide Group-3-compatible faxing capabilities.

The product prints 15 pages per minute (ppm) on letter-size paper or 14 ppm on A4. With 1200 dpi printing resolution, the product has exceptional text and graphics print quality. The simple control panel and improved paper handling make this product very easy to use.

The main input tray has a 250-sheet capacity for continuous, multiplepage printing. The priority input tray allows for manual feed of up to ten sheets. Both trays are center-justified for all supported paper sizes. The output bin holds up to 125 sheets.

The product has a very fast first-page-out, at less than ten seconds. The formatter board contains 4 MB of ROM, 32 MB of RAM, and an embedded 32-bit Coldfire V3 processor. There is one DIMM slot available for font or memory expansion (supporting an 8 MB, 16 MB, 32 MB, or 64 MB DIMM).

The print engine has a 1,000 average (10,000 peak) page-per-month duty cycle. The standard toner life is 2,500 pages, and the highcapacity toner life is 3,500 pages with 5% toner coverage.

Print cartridge information

The print cartridge is designed to simplify replacement of the major consumable parts. The print cartridge contains the printing mechanism and a supply of toner.

At five percent page coverage, a standard print cartridge will print approximately 2,500 pages. However, a cartridge should print more pages if it regularly prints pages with less coverage, such as short memos. The cartridge might print fewer pages if heavy or bold print is used.

For best results, always use a print cartridge before the expiration date stamped on the cartridge box.

Refilled print cartridges

While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty period or while the product is under a maintenance contract, it is not recommended for the following reasons:

 Repairs resulting from the use of refilled cartridges are not

covered under Hewlett-Packard warranty or maintenance contracts.

 Hewlett-Packard has no control or process to ensure that a

refilled cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also cannot predict the long-term reliability effect on the product from using different toner formulations found in refilled cartridges.

 The print quality of HP LaserJet print cartridges influences the

customer’s perception of the product. Hewlett-Packard has no control over the actual print quality of a refilled cartridge.

 Parts that are critical to print quality may not be replaced when

the cartridge is refilled with toner.

Recycling print cartridges

In order to reduce waste, Hewlett-Packard offers a recycling program. Cartridge components that do not wear out are recycled. Plastics and other materials are recycled. Hewlett-Packard pays the shipping

EN Print cartridge information 25

Page 28

costs from the user to the recycling plant (within the United States). To join this recycling effort, follow the instructions inside the print cartridge box.

Fax controls

Fax capability is available on the HP LaserJet 3330 product only. Use the fax controls to send and receive faxes. These controls and the fax menu or software are used to change commonly used fax settings.

Figure 5. Fax controls

The HP 3330 has extensive faxing capabilities. This manual describes only sending a fax to one recipient and receiving a fax. For a full description of the fax capabilities, see “Faxing” in the User Guide on the product CD.

To send a fax to one recipient

1 Dial the fax number using one of the following methods:

• Use the alphanumeric buttons on the product’s control panel.

• If the fax number you are calling has been assigned to a one-

touch key, press that key.

• If the fax number you are calling has a speed-dial code, press

speed dial, enter the speed-dial code using the alphanumeric

buttons, and press

Note When dialing with the alphanumeric buttons, include any pauses

or other needed numbers, such as an area code, an access code for numbers outside a PBX system (usually a 9 or 0), or a longdistance prefix. For more information, see “Using dialing characters” in the User Guide on the product CD.

When the last page of the fax has exited the product, you can start sending another fax, copying, or scanning.

To fax to numbers you use regularly, you can assign a one-touch key or speed-dial code as described in the User Guide on the product CD. If you have electronic phone books available, you may be able to use them for selecting recipients. Electronic phone books are generated with third-party applications.

Note If y ou want to improve the quality of a paper document before faxing

it, scan the document, straighten or clean the image, and send it as a fax from the software. For more information, see the product software Help.

To receive faxes when you hear fax tones

In general, incoming faxes to the product are automatically received. However, if other devices are connected to the same phone line, the product may not be set to answer automatically.

If the product is connected to a phone line that receives both fax and phone calls, and you hear fax tones when you answer the extension phone, receive the fax in one of two ways:

 If you are near the product, press fax/send on the control panel.  Press 1-2-3 in sequence on the extension phone keypad, listen

for fax transmission sounds, then hang up.

Note F or the 1-2-3 sequence to work, the extension phone setting must

be set to Yes in the fax menu.

Guidelines for using media

Paper and Transparencies

Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes, and curled or bent edges. Check the label on the paper package for details about the type of paper (such as bond or recycled).

Some paper causes print quality problems, jamming, or damage to the printer.

Note Do not use letterhead that is printed with low-temperature inks,

such as those used in some types of thermography, raised letterhead, or colored paper or preprinted forms that use inks incompatible with the printer temperature (200° C or 392° F for

0.1 second).

Transparencies must be able to withstand 200° C (392° F), the printer’s maximum temperature.

Labels

When selecting labels, consider the quality of the following factors:

 Adhesives: The adhesive material should be stable at 200° C

(392° F), the printer’s maximum temperature.

 Arrangement: Only use labels with no exposed backing between

them. Labels can peel off sheets that have spaces between the labels, causing serious jams.

 Curl: Prior to printing, labels must lie flat with no more than

13 mm (0.5 in) of curl in any direction.

 Condition: Do not use labels with wrinkles, bubbles, or other

indications of separation. Never use a sheet of labels that has already been run through the printer.

Envelopes

Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends on the quality of the envelopes. When selecting envelopes, consider the following factors:

 Weight: The weight of the envelope paper should not exceed 105

 Construction: Prior to printing, envelopes should lie flat with less

(28 lb), or jamming might result.

g/m

than 6 mm (0.25 in) curl and should not contain air. Envelopes that trap air may cause problems.

 Condition: Make sure that the envelopes are not wrinkled,

nicked, or otherwise damaged.

 Sizes: From 90 x 160 mm (3.5 x 6.3 in) to 178 x 254 mm

(7 x 10

in).

Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing.

EN Guidelines for using media 47

Page 50

Envelopes with double-side seams

An envelope with double-side-seam construction (vertical seams at both ends of the envelope rather than diagonal seams) is more likely to wrinkle. Make sure the seam extends all the way to the corner of the envelope as shown in the following illustration:

Acceptable

Unacceptable

Envelopes with adhesive strips or flaps

Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the printer: 200° C (392° F). The extra flaps and strips might cause wrinkling, creasing, or jams.

Card stock and heavy media

For optimum performance, do not use paper heavier than 157 g/m2 (42-pound). Paper that is too heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print quality, or excessive mechanical wear.

Note You might be able to print on heavier paper if you do not fill the

input tray to capacity and if you use paper with a smoothness rating of 100 to 180 Sheffield.

Basic functions

This chapter presents a functional overview of the HP LaserJet 3300mfp series. The following systems are discussed:

 formatter functions  scanner and ADF functions and operation  printer functions and operation

• ECU (engine controller unit) system/power system

• image formation system

• paper-feed system (printer) and document-feed system

(document scanner)

 LIU (fax) functions and operation

The full product consists of:

 the scanner (flatbed/ADF)  the printer  the line interface unit (LIU).

Each of these three systems brings its own characteristic functionality to the product: scanning, printing, and telecommunications respectively. In addition, these systems combine forces to complete the functionality offering of the product.

 The scanner and printer work together to make copies.  The scanner and LIU work together to send faxes.  The LIU and printer work together to receive faxes.

Operation sequences of the printer are controlled by the ECU. Operation sequences of the LIU and document scanner are controlled by the formatter.

Formatter system

The formatter coordinates the major systems. It is responsible for the following:

 controlling the scanner formatter  formatting and controlling copies  receiving and processing print data from the printer interface  monitoring the control panel and relaying printer status

information

 developing and coordinating data placement and timing with the

print engine

 communicating with the host computer through the bidirectional

interface

 communicating document data to and from the LIU

The formatter receives print data from the bidirectional Extended Capabilities Port (ECP) mode interface or Universal Serial Bus (USB) interface and converts it into a dot image. The ECU synchronizes the image formation system with the paper-feed system and signals the formatter to send the print image data. The formatter sends the print image data (dots) in the form of a video signal, and the printing process begins.

Central processing unit

The formatter incorporates an embedded Coldfire V3 microprocessor operating at 90 MHz.

Line Interface Unit (LIU)

The LIU provides the required safety isolation, signal coupling, and impedance matching between the telephone line and the modem chipset.

Scanner formatter PCA

The scanner formatter manages the functions of the control panel, and controls audio, scanning, and the ADF. It relays scanning data, control panel data, and other control data to the main formatter PCA.

76 Chapter 4 - Operational overview EN

Page 79

Flash memory or ROM

The formatter system includes firmware code that controls the product stored in either flash memory or ROM, depending on when the product was manufactured. Initially the formatters in all manufactured units are built with flash memory. As the product manufacturing matures, the code is stored in standard read-onlymemory (ROM).

Units with firmware code in flash memory allow the firmware code to be recovered or updated. The firmware update/recovery process is described in Chapter 6. Units with firmware code in ROM will not require firmware code recovery or updating.

Standard Boot Process

When the product is unplugged or the power is off, the firmware code is stored on the formatter in two blocks. The first block of code is an executable boot block (about 64K of code). The second block of code is a compressed version of the product control code.

When the product is powered up, the boot block decompresses the product control code and stores it in RAM. Then the product performs a full startup with the control code running from RAM.

Product startup messages

The LED display contains different messages depending upon the progress of the boot process:

Page 80

RAM

 One bank of Non-Volatile RAM (NVRAM) stores parameters.  Dynamic random access memory (DRAM) provides temporary

storage of the product program code plus copy, scan, and print

data.

Parallel interface or Universal Serial Bus interface

The formatter receives incoming data through its bidirectional ECP or USB interface. These interfaces provide high-speed, two-way communication between the product and the host, allowing you to change product settings and monitor product status from the host computer.

Control panel

The control panel configuration varies by model in the HP LaserJet 3300mfp series. For example, only the HP LaserJet 3330mfp has the fax buttons.

The HP LaserJet 3300mfp series control panel consists of:

 up to six groups of buttons to control fax, copy, scan, and

configuration functionality (with all six on the HP LaserJet 3330).

 a 2 x 16 LCD display for display of status, menus, and messages.  up to two front panel status lights (one by the cancel button and

one by the

fax/send button on the HP LaserJet 3330).

Draft mode

Depending on which driver is used, selecting draft or EconoMode from the driver allows the product to use approximately fifty percent less toner, extending the life of the print cartridge.

MEt

HP MEt effectively doubles the standard memory through a variety of font and data-compression methods.

Page 81

Enhanced I/O

The Enhanced I/O feature allows product memory to be used for storing dat a rece iv ed fr om the ho st co mp u ter . Wh en En ha n ce d I/O is enabled, you can send more data to the product in shorter amounts of time, which allows you to return to your application sooner. Enhanced I/O has the following options:

 Auto—allows the product to use Enhanced I/O memory

allocation to increase the speed of data transfer from the host

computer to the product, if necessary. The default setting is Auto.

 Off—uses the minimum amount of product memory for storing

data sent from the host computer.

 Page Protect—allows the formatter to create the entire page

image in page buffer memory before physically moving the media

through the printer. This process ensures that the entire page will

be printed.

Page complexity (ruling lines, complex graphics, or dense text)

can exceed the printer’s ability to create the page image fast

enough to keep pace with the image formation process. If Page

Protect is disabled and a page is too complex, the page might

print in parts (for example, the top half on one page and the

bottom half on the next page). Some print-data loss is likely in

these instances, and the product will display an error message.

PJL overview

Printer Job Language (PJL) is an integral part of configuration, in addition to the standard Printer Command Language (PCL). With standard ECP cabling, PJL allows the product to perform functions such as:

 Two-way communication with the host computer through a

bidirectional parallel or USB connection. The product can

communicate information to the host (such as the control panel

status).

 Isolation of print environment settings from one print job to the

next. For example, if a print job is sent to the printer in landscape

mode, the subsequent print jobs print in landscape only if they

are formatted for landscape printing.

Scanner and ADF functions and operation

Scanner Functions

The scanner uses a light source, a color-separation method, and a Charge Coupled Device array (CCD) to collect optical information about the document and transform that into an image file. The scanner consists of:

 a lamp (cold fluorescent bulb)  five mirrors and a lens  a CCD

Scanner Glass

CCFL Lamp

600 ppi CCD

Lens

Figure 11. Optical diagram of scanner

The scanner lamp illuminates a small strip of the document (called

raster line). The light is directed via the mirrors through the lens to

the the CCD. The CCD senses and records the light, creating an analog representation of the raster line. If using the ADF, the document then advances in the ADF to the next raster line. If using the flatbed, the scanner module advances to the next raster line. This advancing and collection process continues up to the end of the sheet.

80 Chapter 4 - Operational overview EN

Page 83

The image data is collected in the scanner formatter where it is processed and sent to the formatter. The formatter then handles the image data, outputting it as a copy, sending it through the LIU as a fax, or directing it to the computer as scanner output.

The image data collected is 600 pixels per inch. Each pixel has 8 bits for each of the three colors (256 “grey” levels for each color) or a t ota l of 24 bits per pixel (24-bit color).

Scanner Operation

Upon power-up and periodically at other times, the scanner assembly moves systematically to locate its home position. It then calibrates itself to a white label located under the glass at the right end of the scan tub.

If a document is detected in the ADF when a copy or scan is initiated (from software or control panel), the scan module moves to the left side of the scan tub and stops. The image is acquired as the paper is fed through the ADF past the scanner module.

If no document is detected in the ADF, or if the model does not have an ADF, the scan module acquires the image from the flatbed glass while slowly moving within the scan tub.

ADF Operation

Standby (paper loading) mode: In standby mode, the pickup roller

is up and the stack stop is down, preventing the user from inserting the document original in too far. When a document is inserted properly, it is detected by the paper-present sensor.

The standard operation of the ADF consists of the pick, feed, and lift steps.

Pick: Upon receipt of a copy or scan command, the ADF motor

engages the gear train to lower the pick roller assembly and raise the stack-stop. The first roller is called the pre-pick roller and serves to move the top few sheets forward into the ADF. The next roller is the pick roller. This roller contacts the ADF separation pad which separates multiple pages into single sheets.

Feed: The single sheet continues through the path. Along the way, it

is detected by the form sensor a set distance from the ADF glass. This alerts the scanner to start when the page reaches the glass. The scanner acquires the image, one raster line at a time, until the end of the page is detected and the page is ejected. The pick and feed steps are repeated as long as paper is detected in the ADF input tray.

EN Scanner and ADF functions and operation 81

Page 84

Lift: When no more paper is detected in the ADF input tray and the

trailing edge of the last page is detected by the form sensor, the last sheet is ejected and the motor turns in a sequence which lifts the pick roller assembly to standby or “paper loading” mode again.

The ADF will not function with the ADF door open. The paper path is incomplete if the ADF lid is lifted from the glass.

ADF Jam Detection

The ADF has two sensors that detect paper. The paper present sensor detects the presence of media in the ADF input tray. The form sensor detects media moving through the ADF. If a jam is detected, the ADF immediately stops the paper feeding and the control panel displays a jam message.

A jam can be detected under any of the following conditions:

 Document feeder jam—When documents are detected as

present in the ADF input tray, and a command to copy, scan or

fax is received, the scan module travels to the left side of the

scan assembly and stops beneath the ADF scanner glass. The

ADF then attempts three times, or for about ten seconds, to

advance the paper to the form sensor. If the paper does not

advance, the scan module travels back to the home position on

the right side of the scanner assembly. The control panel displays

the message Doc. Feed Mispick. Reload.

 Long document jam—If the paper has advanced to trigger the

form sensor, but the trailing edge is not detected within the time

allowed for a 15 in document (the maximum allowable page

length for the ADF), the scanner returns to the home position at

the right side of the scanner assembly. The control panel displays

the message Doc. Feed Jam.

 Stall jam—When a page that is less than 15 in long has

advanced to the form sensor but has not left it within the expected

time, the paper has probably stalled or jammed. The scanner

returns to the home position at the right side of the scanner

assembly. The control pan el disp lay s the mes sa ge Doc. Feed

Jam.

 Other—If the paper stops in the ADF and the scan module

remains under the ADF scanner glass, an internal firmware error

has probably occurred. This is usually remedied by cycling the

power.

Printer engine control system

Paper motion monitoring and control The ECU controls paper motion in the printer by continuously

monitoring the various paper sensors and coordinating the timing with the other print processes.

For a detailed explanation of paper movement and the interaction of the photo sensors and solenoid with the paper movement process, see “Printer paper-feed system” on page 94.

Motor The motor is controlled by the ECU. The motor provides all of the

printer paper movement.

Printer laser/scanner drive

The ECU sends signals to the laser/scanner assembly to modulate the lase r diode “on” and “off” and to drive the laser/scanner motor.

Power system on ECU

The AC, DC, and high-voltage power supply circuits are all contained within the ECU.

AC power distribution

The AC power circuitry supplies AC voltage whenever the power cord is connected to the AC power source. AC voltage is distributed to the DC power supply circuitry and to the AC driver circuitry, which controls AC voltage to the fuser assembly heating element.

DC power distribution

The DC power distribution circuitry, located on the ECU, distributes +3.3 Vdc, +5 Vdc, +24 Vdc, and +32 Vdc as follows:

Overcurrent/overvoltage

There are two overvoltage devices in this product:

 Fuse F101 provides overcurrent protection for the fusing system

circuitry.

 Fuse F102 provides overcurrent protection to the printer DC

power supply circuitry. You can check or replace the fuses by removing the back cover

(page 164). In addition, the +24 Vdc and +3.3 Vdc power circuitry contains an

overcurrent protection circuit that automatically shuts off the output voltage when an overcurrent condition occurs as a result of a short or an abnormal voltage on the load side. These circuits automatically reset.

High-voltage power distribution

The high-voltage power supply applies an overlap of DC and AC voltage to the primary charging roller and the developing roller. This circuit also applies a positive or negative DC voltage to the transfer roller according to the instructions from the engine control unit.

This circuit also controls the image density by changing the primary AC voltage and the developing AC bias according to the print density setting.

Image formation system

Laser printing requires the interaction of several different technologies including electronics, optics, and electrophotographics to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation consists of seven processes:

Conditioning stage

Figure 17. Image formation block diagram

Writing stage

Print cartridge

As the focal point of the image formation system, the print cartridge contains toner and houses the cleaning, conditioning, and developing stages of the process. The print cartridge contains the photosensitive drum, primary charging roller, developing station, toner cavity, and cleaning station. By including these components (which wear, degrade, or are consumed) in the replaceable print cartridge, the need for many service calls is eliminated. The special photosensitive properties of the drum form an image on the drum surface and then transfer the image to media.

CAUTION The print cartridge does not include a light-blocking shutter. Do not

expose the drum to light, which can permanently damage the drum.

Protect the print cartridge whenever you remove it.

EN Printer functions and operation 91

Page 94

The seven image-formation processes

1 Conditioning stage (primary charging)—This process applies

a uniform negative charge to the surface of the drum with the

primary charging roller, which is located in the print cartridge. The

primary charging roller is coated with conductive rubber. An AC

bias is applied to the roller to erase any residual charges from

any previous image. In addition, the primary charging roller

applies a negative DC bias to create a uniform negative potential

on the drum surface. The print density setting modifies the DC

voltage.

2 Writing stage (scanning exposure)—During this process, a

modulated laser diode projects the beam onto a rotating scanning

mirror. As the mirror rotates, the beam reflects off the mirror, first

through a set of focusing lenses, then off a mirror, and finally

through a slot in the top of the print cartridge, and onto the

photosensitive drum. The beam sweeps the drum from left to

right, discharging the negative potential wherever the beam

strikes the surface. This creates a latent electrostatic image,

which later is developed into a visible image.

Because the beam sweeps the entire length of the drum while the

drum rotates, the entire surface area of the drum can be covered.

At the end of each sweep, the beam strikes the beam-detect lens,

generating the beam-detect signal (BD signal). The BD signal is

sent to the ECU where it is converted to an electrical signal used

to synchronize the output of the next scan line of data.

3 Developing stage—During this process, the latent electrostatic

image is present on the drum. The toner particles obtain a

negative surface charge by rubbing against the developing

cylinder, which is connected to a negative DC supply. The

negatively charged toner is attracted to the discharged (exposed,

grounded) areas of the drum, and it is repelled from the

negatively charged (unexposed) areas.

4 Transfer stage—During this process, the toner image on the

drum surface is transferred to the media. The transfer roller

applies a positive charge to the back of the media, which attracts

the negatively charged toner on the drum surface to the media.

After separation, the drum is cleaned and conditioned for the next

image.

92 Chapter 4 - Operational overview EN

Page 95

5 Separation stage—

During this process, the media separates from the drum. To stabilize the feed system and prevent toner dropouts on the printed image at low temperature and humidity, the static eliminator reduces the charge on the back of the media.

6 Fusing stage—During this process, the heat and pressure fuse

the toner into the media to produce a permanent image. The media passes between a heated fusing element and a soft pressure roller, which melt the toner and press it into the media.

7 Drum-cleaning stage—During this process, the cleaning blade

is in contact with the surface of the drum at all times. As the drum rotates during printing, the cleaning blade wipes excess toner off the drum and stores it in the waste toner receptacle.

EN Printer functions and operation 93

Page 96

Printer paper-feed system

The main input tray and the priority input tray merge into one main input area. Media placed in any of these areas activates the paperout sensor (PS201), which informs the ECU that media is present. The following steps occur when the product receives a print job:

Step 1 The ECU activates the laser/scanner assembly and the

motor. Paper motion begins when the ECU energizes the solenoid (SL001).

Step 2 The paper pickup roller rotates once. The paper lift plate

pushes the media against the pickup roller.

Step 3 The pickup roller grabs the top sheet and advances it to the

feed assembly drive rollers. To ensure that only one sheet is fed, a main separation pad and two subpads hold the remainder of the stack in place.

Step 4 The feed assembly drive rollers advance the media to the

top-of-page sensor (PS402). This sensor informs the ECU of the exact location of the leading edge of media, so that the image being written on the photosensitive drum can be precisely positioned on the page.

Step 5 The feed assembly drive rollers then advance the media to

the transfer area where the toner image on the photosensitive drum is transferred to the media.

Step 6 After the image is transferred, the media enters the fuser

assembly where heat from the fuser and pressure from the pressure roller permanently bond the toner image to media. The paper delivery sensor (PS401) determines that the media has successfully moved out of the fusing area.

Step 7 The fuser assembly exit rollers deliver media to either the

paper output bin or the straight-through output path, depending upon the position of the straight-through output path door.

Jam detection

The paper-out sensor (PS201) detects the presence of media in either the priority input tray or the main input tray. The top-of-page sensor (PS402) and the paper delivery sensor (PS401) detect media moving through the printer. If a jam is detected, the ECU immediately stops the printing process and displays a jam message on the control panel.

A jam can be detected under any of the following conditions:

 Pickup delay jam—Media does not reach the top-of-page

sensor (PS402) after the pickup solenoid (SL001) has been turned on twice (the original pickup plus a retry) within 2.8 seconds.

 Pickup stationary jam—The top-of-page sensor (PS402) does

not detect the trailing edge of media within 4.6 seconds of detecting the leading edge.

 Delivery-delay jam—The paper delivery sensor (PS401) does

not detect the leading edge of media within 2.1 seconds after the top-of-page sensor (PS402) detects the leading edge.

 Wrapping jam—The paper delivery sensor (PS401) does not

detect the trailing edge of the media within 1.5 seconds after the top-of-page sensor (PS402) detects the leading edge and within ten seconds after the paper delivery sensor (PS401) detects the leading edge.

 Delivery-stationary jam—The paper delivery sensor (PS401)

does not detect the leading edge of media within 2.2 seconds after the top-of-page sensor (PS402) detects the trailing edge.

 Residual paper jam—The top-of-page sensor (PS402 ) or the

paper delivery sensor (PS401) detect media in the initial rotation period.

3 Top-of-page sensor (PS402) detects the leading and trailing

edges of the paper. It synchronizes the photosensitive drum and the top of the paper.

4 Engine test switch (SW201), see “Engine test” on page 200 for an

explanation of the switch.

5 Door-open switch (SW301) detects whether or not the print

cartridge door is closed and the print cartridge is installed properly. Printing cannot continue until the print cartridge door is closed and the print cartridge is in its correct position.

6 Solenoid (SL001) activates the pickup roller. 7 Paper-out sensor (PS201) senses when paper is in the main

input tray or the priority input tray.
