Extended warranty
In most countries/regions, HP Care Pack provides additional coverage, beyond standard
warranty, for the HP device and for all HP-supplied internal components. This hardware
maintenance can uplift the standard warranty, for example, from next-day to same-day
service, and/or extend it up to 5 years. HP Care Pack can also provide Express Exchange or
onsite service. For more information, see the support flyer that came with your device for the
appropriate phone numbers and information.

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 5 percent page coverage, a standard print cartridge will print approximately 2,500 pages.
As page coverage increases, yield decreases. These estimates are only approximate; usage
conditions and print patterns can cause results to vary.
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 controls or processes to ensure that a refilled cartridge
functions at the high level of reliability of a new HP LaserJet print 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 might not be replaced when the cartridge is refilled
with toner.
HP LaserJet printing supplies
In many countries/regions, this product's printing supplies (for example the print cartridge)
can be returned to HP through the HP Printing Supplies Returns and Recycling Program. An

Guidelines for using media
Use the information in this section to choose the proper print 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.

For copy or fax jobs, select less
paper curl in the service menu. For
print jobs, select a lighter-weight
media type from the printer driver or
the HP Toolbox.
Do not use media that has cutouts or
perforations.
Labels
For best results, use only HP-brand labels. To order HP supplies, visit http://www.hp.com.
When selecting labels, consider the following factors:
● Adhesives: The adhesive material should be stable at 200° C (392° F), the product's
maximum temperature.
● Arrangement: Use only labels that have 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 inch) of curl in
any direction.
● Condition: Do not use labels that contain 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 g/m
jamming might result.
● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch)
curl and should not contain air. Envelopes that trap air can cause problems.
● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise
damaged.
● Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 inches) to 178
by 254 mm (7 by 10 inches).
Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope
might wrinkle during printing.

ENWW Guidelines for using media 37
Page 51
Envelopes with double-side seams
An envelope with double-side-seam construction has vertical seams at both ends of the
envelope rather than diagonal seams. This style is more likely to wrinkle during printing.
Make sure that the seam extends all the way to the corner of the envelope as shown in the
following illustration:
Note
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 that are compatible with the heat (200° C, or 392° F) and pressure in
the printer. The extra flaps and strips might cause wrinkling, creasing, or jams.
Envelope storage
Store envelopes flat to ensure good print quality. If air is trapped in and envelope, creating
an air bubble, the envelope might wrinkle during printing.
Card stock and heavy media
Some card stock performs better than others because the construction is better suited for
feeding through a laser device. For optimum performance, do not use media that is heavier
than 163 g/m
jams, poor toner fusing, poor print quality, or excessive mechanical wear.
You might be able to print on heavier media if you do not fill the input tray to capacity and if
you use media that has a smoothness rating of 100 to 180 Sheffield. Use the straightthrough paper path for heavier media.

Loading media
This section provides information about loading media in the input trays.
Media input tray
The media input tray holds up to 250 sheets of 75-g/m2 (20-lb) paper or a 25-mm (0.98-inch)
stack of heavier media. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.
Priority input tray
The priority input tray holds up to ten pages of 75-g/m2 (20-lb) paper or one envelope,
transparency, or card. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.
If you try to print on media that is wrinkled, folded, or damaged in any way, a jam might
occur. See the user guide on the product CD for more information.
Note
When you add new media, make sure that you remove all of the media from the input tray
and straighten the stack of new media. This helps prevent multiple sheets of media from
feeding through the printer at one time, reducing jams.
Specific types of media
● Transparencies and labels: Load transparencies and labels with the top forward and
the side to be printed on facing up. See the user guide on the product CD for more
information.
● Envelopes: Load envelopes with the narrow, stamp side forward and the side to be

You must use the flatbed to scan or copy small or delicate originals (such as newsprint,
business cards, and photos), or documents that have tears, perforations, or punch holes. If
you want to fax such items, first make a copy on the flatbed and then fax the copy.
Perform the following actions to minimize the possibility of jams:
● Remove self-stick notes.
● Remove staples and paper clips.
● Straighten any curls, folds, or wrinkles in documents before putting them into the
document feeder tray.
● Do not insert any document that contains glue, correction fluid, or wet ink.
● Do not insert gum-backed paper or labels.
● Avoid multiple-copy forms.
● Do not scan originals that are larger or smaller than supported size limitations. See the
user guide on the product CD for more information.
To obtain good results, it is important to use the correct re-entry and color settings for the
job. See the user guide on the product CD for more information.

Printer output paths
The HP LaserJet 3380 all-in-one has two output paths. Use the main output bin when
printing normal and large, collated documents. Use the straight-through output path when
printing envelopes, transparencies, heavy media, or any media that tends to curl when
printed.
Output bin and straight-through output path
The output bin is located between the scanner and the printer. Printed media is collected
here in the correct sequence when the straight-through output door is closed.
To use the straight-through output path, open the straight-through output door on the rear of
the product. Multipage documents are delivered in reverse order when the straight-through
output door is open.
Figure 2-6. Output bin

Formatter system
The formatter coordinates the major systems. It is responsible for the following tasks or
actions:
● controlling the motor controller board
● 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 fax data to and from the LIU
The formatter receives print data from the bidirectional enhanced 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 32-bit Coldfire V4e processor 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 that is located on the formatter.
Motor controller PCA
The motor controller PCA contains motor-driver circuitry for the ADF motor and the scanmodule position motor. The motor controller PCA also provides electrical interface from the
formatter to the control-panel PCA and to the speaker.
Flash memory
The formatter system includes firmware code that controls the product. The code is stored in
flash memory, which allows the firmware code to be recovered or updated. The firmware
update and recovery process is described in
Troubleshooting.
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 64 K of
code). The second block of code is a compressed version of the product control code.
When the product is turned on, 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.
ENWW Formatter system 73
Page 86
Product startup messages
The LED display contains different messages depending upon the progress of the boot
process:
Table 4-3. Product startup messages

and the product is ready for use.
The flash memory requires a
DIMM recovery of the firmware
code (see chapter 6).
DIMM recovery of the firmware
code (see chapter 6).
Begin using the product.
RAM
The product contains two types of random-access memory (RAM):
● One bank of nonvolatile RAM (NVRAM) stores parameters.
● Dynamic random access memory (DRAM) provides temporary storage of the product
program code along with copy, scan, and print data.
Parallel interface or universal serial bus (USB) 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 consists of the following features:
● six groups of buttons to control fax, copy, scan, and configuration functionality
● a 2-by-16 LCD display that shows status, menus, and messages
● two front-panel status lights (one next to the
button and one next to the
FAX/SEND
CANCEL
button)
EconoMode (Draft mode)
When you select EconoMode in the printer driver, the product uses less toner, which
extends the life of the print cartridge. Using EconoMode produces a lighter image because
less toner is on the page.
74 Chapter 4 Operational overview ENWW
Page 87
MEt
HP Memory Enhancement technology (MEt) effectively doubles the standard memory
through a variety of font- and data-compression methods.
Enhanced I/O
The enhanced I/O (EIO) feature allows product memory to be used for storing data received
from the host computer. When EIO is enabled, you can send more data to the product in
shorter amounts of time, so that you can return to the software program more quickly. The
EIO feature has the following options:
● Auto —the product uses EIO memory allocation to increase the speed of data transfer
from the host computer to the product, if necessary. The default setting is Auto.
● Off —the minimum amount of product memory is used to store data that is sent from the
host computer.
● Page Protect—the formatter creates 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 sections (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 an error message will appear on the control-panel
display.
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, the product can use PJL to
perform the following functions:
● Two-way communication with the host computer through a bidirectional parallel
connection. The product can communicate information to the host (such as the controlpanel status).
● Isolation of print environment settings from one print job to the next. For example, if
a print job is sent to the product in landscape mode, the subsequent print jobs print in
landscape only if they are formatted for landscape printing.
ENWW Formatter system 75
Page 88
Scanner and ADF functions and operation
The following sections describe how the document scanner and the automatic document
feeder (ADF) function.
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 these elements:
● a lamp (cold-cathode fluorescent bulb)
● five mirrors and a lens
● a CCD
Scanner Glass
CCFL Lamp
600 ppi CCD
Figure 4-3. Optical diagram of scanner
The scanner lamp illuminates a small strip of the document (called the raster line). The
mirrors direct the light through the lens to the CCD. The CCD senses and records the light,
creating an analog representation of the raster line. If the ADF is being used, the document
then advances in the ADF to the next raster line. If the flatbed is being used, the scanner
module advances to the next raster line. This advancing and collection process continues to
the end of the sheet.
The image data is collected in the motor controller board, 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 for scans is 600 pixels per inch (ppi). The image data collected for
copies is 300 ppi. Each pixel has 8 bits for each of the three colors (256 grayscale levels for
each color) or a total of 24 bits per pixel (24-bit color).
Lens
76 Chapter 4 Operational overview ENWW
Page 89
Scanner operation
At startup and periodically at other times, the scanner assembly moves systematically to
locate its home position. It then calibrates to a white strip located under the glass at the right
end of the scan tub.
If the product detects a document in the ADF when a copy or scan is initiated (from the
software or the 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, 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 original document too far. When a document
is inserted correctly, the paper-present sensor detects its presence.
The standard operation of the ADF consists of the pick, feed, and lift steps.
Pick: When it receives a copy or scan command, the ADF motor engages the gear train to
lower the pickup-roller assembly and raise the stack-stop. The first roller, called the pre-pick
roller, moves the top few sheets forward into the ADF. The next roller is the pickup 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, the form sensor, which is
a set distance from the ADF glass, detects the sheet. This alerts the scanner to start when
the page reaches the glass. The scanner acquires the image, one raster line at a time, until
it detects the end of the page. The page is then ejected. The pick and feed steps are
repeated as long as paper is detected in the ADF input tray.
Lift: When no more paper is detected in the ADF input tray and the form sensor detects the
trailing edge of the last page, the last sheet is ejected and the motor turns in a sequence that
lifts the pick roller assembly to standby (paper-loading) mode again.
The ADF will not function when the ADF lid is open. The paper path is incomplete if the ADF
lid is lifted from the glass.

Document scanner path
The paper-present sensor determines if paper is in the ADF. The form sensor detects the top
and bottom edges of the document. One other sensor detects an open ADF door.
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 a jam message appears
on the control-panel display.
A jam can be detected under any of the following conditions:
● Document-feeder jam—When documents are detected 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 message Document feeder mispick. Reload. appears on
the control-panel display.
● 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 381-mm (15-inch) 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 message Doc feeder jam. Clear,
Reload. appears on the control-panel display.
● Stall jam—When a page that is less than 381 mm (15 inches) 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 message Doc feeder jam. Clear, Reload. appears on the control-panel
display.
● 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.

ECU loads
Power system within the 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:

supply circuit shows the high-voltage power supply circuit.
Figure 4-7. High-voltage power
Figure 4-7.
ENWW Printer functions and operation 83
High-voltage power supply circuit
Low-voltage power distribution
The low-voltage power supply circuit converts ac power into +24 Vdc, +5 Vdc, and +3.3 Vdc
as required by the printer. The +24 Vdc is divided into +24 V, which is supplied constantly
from the low-voltage power supply circuit, and +24 U, which is supplied to the high-voltage
power supply circuit and which acts as the door-open detection. When the top cover is open,
the door-open switch (SW301) cuts the +24 U to the high-voltage power supply circuit.
The circuit contains a fuse for overvoltage protection. FU101 breaks and cuts power if
overcurrent flows through the power cord. FU102 (on 110-127 V models) breaks at a lower
amperage, as required for lower-voltage units.
In addition, the +24 Vdc and +3.3 Vdc power circuitry contains an overcurrent protection
circuit that automatically shuts off dc voltage output to prevent power-supply failures if
current flow is excessive or voltage generation is abnormal. The circuit automatically resets
itself when the printer is turned off.
Page 96
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 photosensors and
solenoid with the paper-motion process, see
Printer paper-feed system.
Motors
The ECU controls the motors. The main motor provides all of the paper movement in the
printer. The fan motor rotates the fan to cool the printer.
Printer laser/scanner drive
The laser/scanner system is controlled by the ECU, which sends laser control signals CNT0,
CNT1, and CNT2, and by the formatter, which sends video signals /VDO1, VDO1, /VDO2,
and VDO2.
Figure 4-8. Overview of laser/scanner operation
84 Chapter 4 Operational overview ENWW
Page 97
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:
Figure 4-9. Image-formation block diagram
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 that synchronizes 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.
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.
ENWW Printer functions and operation 85
Page 98
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.
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.
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 paper detection sensor (PS931), 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 (SL1).
Step 2 The paper-pickup roller rotates once. The paper-lift plate pushes the media against the
pickup roller.
Step 3 The pickup roller moves 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 paper-top sensor (PS911).
This sensor informs the ECU of the exact location of the leading edge of media, so that
the image that is 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 (PS921) 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, according to the position of the straight-through output path
door.

Jam detection
The paper-detection sensor (PS931) detects the presence of media in either the priority
input tray or the main input tray. The paper-top sensor (PS911) and the paper-delivery
sensor (PS921) detect media moving through the printer. If a jam is detected, the ECU
immediately stops the printing process and a jam message appears on the control-panel
display.
A jam can be detected under any of the following conditions:
● Pickup delay jam—Media does not reach the paper-top sensor (PS911) after the
pickup solenoid (SL1) has been turned on twice (the original pickup plus a retry) within 2
seconds.
● Pickup stationary jam—The paper-top sensor (PS911) does not detect the trailing
edge of media within 1 second of detecting the leading edge.
● Delivery-delay jam—The paper-delivery sensor (PS921) does not detect the leading
edge of media within 1.5 seconds after the paper-top sensor (PS911) detects the
leading edge.
ENWW Printer functions and operation 87
Page 100
● Wrapping jam—The paper-delivery sensor (PS921) does not detect the trailing edge of
the media within 0.1 second after the paper-top sensor (PS911) detects the leading
edge and 1 second has passed since the paper-delivery sensor (PS921) detected the
leading edge.
● Delivery-stationary jam—The paper-delivery sensor (PS921) does not detect the
leading edge of media within 1.6 seconds after the paper-top sensor (PS911) detects
the trailing edge.
● Residual paper jam—The paper-top sensor (PS911) or the paper-delivery sensor
(PS921) detect media during the initial rotation period.
● Door open jam—The paper-top sensor (PS911) or the paper-delivery sensor (PS921)
detect media while the print-cartridge door is open.
