Printer output paths

T

Top output bin

Printed media is collected in the top output bin when the rear output door is closed. Use the top
output bin when printing most jobs, including documents on average-weight paper, letterhea d,
and transparencies.

The top output bin can hold up to 150 sheets. Prevent more than 150 sheets from accumulating
in the top output bin, or jams can occur.

Rear output door

Print jobs emerge from the back of the printer when the rear output door is open. Use the rear
output door (straight-through paper path) when printing envelopes, labels, heavy- or lightweight
paper, and other thick or special print media (except transparencies). Remove each sheet as it
exits the printer.

Using Printer Status and Alerts

HP color LaserJet 1500 series printers

Printer Status and Alerts is supported only for Microsoft Windows operating systems. The Printer
Status and Alerts software is available to users of both networked and directly con nected
printers.

The software generates messages on the computer regarding the status of the printer and print
jobs. You can receive alert messages that appear when the printer e xperiences a problem. You
can also receive messages only when supplies are low.

You can set alerts options for a single printer that supports Printer Status and Alerts, or you can
set alert options for all printers that support Printer Status and Alerts. For networked printers,
these alerts only ap p ea r for your jobs.

To choose which status messages appear

1 Open Printer Status and Alerts in one of these ways:

• Double-click the Printer Status and Alerts tray icon, which is near the clock in the Tray
Manager.

• O n the Start menu, point to Programs, point to Printer Status and Alerts, and click

Printer Status and Alerts.

2 Click the Options icon in the left pane.
3 Clear the options for the messages that you do not want to appear, and select the options for

the messages that you do want to appear.

4 Under Status Chec k Rate, select how frequently you want the software to update the printer

status information that the software uses to generate the messages. Status Check Rate
might not be available if the network administrator has restricted the rights to this function.

To view status messages and information

On the left side of the window, select the printer for which you want to see information.

Printer Status and Alerts is supported only for Windows 98, NT 4.0, ME, 2000, and XP.
The Printer Status and Alerts software is available to users of both networked and directly

connected printers. Use this software to view the embedded Web server information for a
particular printer. The software also generates messages on the computer regar ding the status
of the printer and print jobs. Depending on how the printer i s connected, y ou can rece ive d iffe rent
messages.

● Networked printers. You can receive regular job status messages that appear every time a

print job is sent to the printer or ev ery time the print job finishes printing. You can also receive
alert messages when two types of problems occur:

• The printer is experiencing a problem, but it can contin ue to print (for example, a tray that
is not being used is out of print media or is open, or a print cartridge is low).

• The printer is experiencing a problem that prevents if from printing (for example, the
printer is out of paper, or a print cartridge is empty).

● Directly connected printers. You can receive alert messages that appear when the printer

experiences a problem. You can also receive messages only when supplies are low.

You can set alerts options for a single printer that supports Printer Status and Alerts, or you can
set alert options for all printers that support Printer Status and Alerts. For networked printers,
these alerts only appear for your jobs.

Note Even if you are setting alert options for all printers, not all options you select can apply to all

printers. For e x ample , if y ou sele ct the opt ion f o r notifying y ou when the print cartridges are low,
then all directly connected printers that support Printer Status and Alerts will generate a message
when the print cartridges are low . However, none of the networked printers will generate this
message, nor will directly connected printers that do not support Printer Status and Alerts.

To choose which status messages appear

1 Open Printer Status and Alerts in one of these wa ys:

• Double-click the Printer Status and Alerts tray icon, which is near th e clock in the Tray
Manager.

• On the Start menu, point to Programs, point to Printer Status and Alerts, and click

62 Maintenance Q2488-90901

Managing supplies

For warranty information about these supplies, see “Limited warranty for the print cartridge and
drum” on page 28.

Supplies life

The life of the imaging drum depends on the number of black-only or color pages that print jobs
require. An HP imaging drum lasts an average of 20,000 pages when printing black-o nly pages
and 5,000 pages when printing color pages. Actual life lies somewhere between these two
numbers, depending on the number of black-only pages you print versus color. The average life
is between 6,000 and 8,000 pages.

The life of a print cartridge depends on the amount of toner that print jobs require . When printing
text at five-percent coverage, an HP cyan, magenta, or yellow print cartridge lasts an average of
4,000 pages, and a black print cartridge lasts an average of 5,000 pages.

Checking and ordering supplies

You can check the supplies status by using the printer control panel, printing a Supplies Status
page, viewing the Toolbox, viewing Printer Status and Alerts, or viewing HP Web Jetadmin
(HP Color LaserJet 2500 series printer only). Hewlett-Packard recommends that you place an
order for a replacement print cartridge when you first receive the Low message for a print
cartridge. The Low message indicates that approximately two weeks of life remain. Whe n you
use a new, authentic HP print cartridge or imaging drum, you can obtain the following types of
supplies information:

● amount of cartridge or drum life remaining

● estimated number of pages that can be printed

● number of pages printed

● other supplies information

To check status and order supplies at the control panel

Do one of the following:

● Check the supplies status lights on the printer control panel. These lights indicate when a

print cartridge or the imaging drum is low or empty. The lights also indicate when a non-HP

Laser/scanner system

The laser/scanner system receives video signals from the dc controller, and then it converts the
signals into latent images on the photosensitive drum. The dc controller controls the laser/
scanner.

Figure 18. Laser/scanner system

ENWW 4 Theory of operation 73

Pickup and feed system

The pickup and feed system consists of several types of feed rollers and sensors. The dc
controller drives the paper and feed system by controlling two motors, two clutches, and the
solenoid.

Two photo-interrupters (PS1 and PS711) detect media as it passes. I f media does not reach or
pass each sensor within the specified time period, the dc controller determines that a jam has
occurred and alerts the video controller circuit.

The following components are identified in figure 19:

● PS1 fusing-delivery paper sensor

● PS711 registration paper sensor

● PS718 tray 1 (multipurpose tray) paper sensor

● PS720 fuser wrap-jam sensor

● DCM701 main motor

● PM702 fuser motor

● SL92 tray 1 pickup solenoid

● CL1 registration clutch

● CL2 roller-engaging clutch

ENWW 4 Theory of operation 75

Paper trays

The dc controller drives the operation sequence of the paper trays. It signals the driver PCB in
optional tray 2 (250-sheet paper tray) and in optional tray 3 (500-sheet paper tray). In option al
tray 2, the printer main motor drives the tray solenoids. In optional tray 3
(HP color LaserJet 2500 series printers only), each driver PCB controls the motors and
solenoids in its paper tray.

The following components are identified in figure 20:

● DCM701 gear-train motor (printer)

● SL9 pickup solenoid (optional tray 2)

● PS716 paper sensor (optional tray 2)

● PS717 paper-feed sensor

Note Only optional tray 2 is shown in figure 20; optional tray 3 is similar.

Figure 20. Optional tray 2 (250-sheet paper tray)

76 Theory of operation Q2488-90901

Jam detection

The registration sensor (PS711) and the fuser se nsor (PS1) det ect media tha t is mo ving th rough
the printer. If a jam is detected, the dc controller immediately stops the printing process and
sends a message to the video controller circuit.

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

● Pickup delay jam. The leading edge of the print media does not reach the registrat ion sensor

(PS711) within 1.1 seconds (tray 1), 1. 7 sec on d s (op tio na l tray 2), or 2.8 seconds (optional
tray 3—HP color LaserJet 2500 series printer only).

● Pickup stationary jam. The registration clutch is on, and the registration sensor (PS711)

does not detect the trailing edge of the media within 3.4 seconds after the start of a re-pickup
operation.

● Fuser wrap-jam. The main CPU detects media inside the fuser front sensor (PS720) when

the power is turned on or after the top cover is closed.

● Delivery delay jam. The registration clutch is on, and the fuser-delivery sensor (PS1) does

not detect the leading edge of the media within 2.3 seconds after the start of a re-pickup
operation.

● Delivery stationary jam. The leading edge of media does not pass the fuser-delivery sensor

(PS1) within 2.4 seconds after it has passed the registration sensor (PS711).

● Door-open jam. The main CPU detects that the top cover is open during a print operation.

● Residual jam. The main CPU detects one or more of the following conditions:

• Power is turned on.

• The printer door is closed after a jam occurrence.

• The registration sensor (PS711) and fusing-delivery sensor (PS1) detect media.

● Paper pickup failure. The sensor (PS717) near the feed roller does not detect media moving

through the printer.

Image-formation system

The image-formation system, which forms a toner image on media, consists of several
interdependent systems:

● electrostatic latent-image-formation system

● developing system

● transfer block

● fuser

● transfer beltcleaning block

● imaging drum (with ITB)

● photosensitive drum

Figure 27. Image-formation system

ENWW 4 Theory of operation 81

Image-formation process

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

1 Latent-image formation
2 Developing
3 Image transfer
4 Fusing
5 Transfer-belt cleaning

The five processes are divided into twelve steps, which are shown in figure 28 and described in
the following sections.

Figure 28. Image-formation process

82 Theory of operation Q2488-90901

Latent-image-formation stage

Step 1: primary charging

A dc bias is applied to the primary charging roller, which transfers a uniform negative pote ntial to
the photosensitive drum.

Figure 29. Step 1: primary charging

Step 2: laser-beam exposure

The laser beam scans the photosensitive drum to neutralize negative charges on parts of the
drum. An electrostatic latent image is formed on the drum where negative charges were
neutralized.

Figure 30. Step 2: laser-beam exposure

ENWW 4 Theory of operation 83

Developing stage

The dev eloping cylind er co mes in co ntact wit h the pho tose nsit ive drum to deposit toner onto the
electrostatic latent image.

Note The charges on the exposed area on the drum are shown as positive in figure 31. The charges

are actually negative, but they are more positive than the charges on the developing cylinder.

Figure 31. Developing block

Step 3: auxiliary developing

The dc bias applied to the blade imports a uniform negative potential to the toner.

Step 4: developing

Toner acquires a negative charge through friction from the developing cylinder and the blade.
When the negatively charged toner comes in contact with the drum, the toner adheres to the
electrostatic latent image. The image on the drum becomes visible because of the toner.

Figure 32. Step 3: developing

84 Theory of operation Q2488-90901

Transfer stage

Step 5: primary transfer

The primary transfer roller , to which a dc po sitive bias is app lied, imparts a positive charge on the
transfer belt. The negatively-charged toner on the drum is transferred to the positively-c harged
transfer belt. This procedure is repeated for each color (yellow, magenta, cyan, and black).

The dc positive bias is increased for each successive color to make sure that all of the colors
adhere to the transfer belt.

Figure 33. Step 4: primary transfer

ENWW 4 Theory of operation 85

Step 6: secondary transfer

The secondary transfer roller, to which a dc positive bias is applied, imparts a positive charge to
the print media. When the print media comes in contact with the transfer belt, the toner is
transferred to the print media.

Note When secondary transfer is complete, a dc negative bias is applied to the secondary transfer

roller to prevent toner on the transfer belt from adhering to the secondary transfer roller.

Figure 34. Step 5: secondary transfer

Step 7: separation

The elasticity of the print media causes it to separate from the transfer belt. A static charge
eliminator aids separation by weakening any electrostatic adhesion.

Figure 35. Step 6: separation

86 Theory of operation Q2488-90901

Fusing stage

Step 8: fusing

The dc negative bias applied to the fusing film strengthens the ho ldin g force of the toner on the
print media and prev ents the toner from scattering.

Figure 36. Step 7: fusing

Step 9: roller charging (auxiliary ITB cleaning roller)

During secondary transfer, not all of the toner on the transfer belt is transferred to the print
media. Toner that remains on the belt is called “residual toner.”

The auxiliary transfer belt cleaning roller, to which a dc positive bias is applied, imparts a positive
charge to the residual toner, strengthening its hold on the transfer belt. This prevents toner from
falling off of the transfe r belt and scattering in the printer.

Figure 37. Step 8: roller charging (auxiliary transfer belt cleaning roller)

ENWW 4 Theory of operation 87

Step 10: roller charging (transfer-belt cleaning roller)

The transfer-belt cleaning roller, to which a dc positive bias is applied, imparts a positive charge
to the residual toner on the tr ansf er belt . This posit iv e charge is stronger tha n the positiv e cha rge
applied in step 8, so the earlier charge now behaves like a negative charge.

Figure 38. Step 9: roller charging (transfer belt cleaning roller)

88 Theory of operation Q2488-90901

Step 11: transfer belt cleaning

A dc positive bias is applied to the transfer belt to produce a difference in p otential between the
belt and the photosensitive drum. This causes residual toner to transfer to the drum.

Figure 39. Step 10: transfer belt cleaning

ENWW 4 Theory of operation 89

Step 12: drum cleaning

The cleaning blade scrapes the residual toner off of the photosensitive drum, where the waste
toner screws collect the toner and deposit it into the waste toner case.

Figure 40. Step 11: drum cleaning

90 Theory of operation Q2488-90901

Print cartridge

The printer has four print cartridges: yellow, magenta, cyan, and black. Each print cartridge
contains a developing cylinder, toner-feed roller, and stirrer. The developer motor rotates these
parts so that each print cartridge can use toner to form a visible image on the drum.

The carousel motor rotates the E-label reader , which commu nicates E-label inf ormation to the dc
controller.

The developing rotary/toner level detection PCB uses an LED (light emitter) and a photodiode
(light receiver) to determine the toner level in each print car tridge.

Figure 41. Print cartridge

ENWW 4 Theory of operation 91

Imaging-drum E-label

The E-label is nonvolatile memory, which is built into the imaging drum and stores usage
information. When the imaging drum is installed in the printer, the E-label makes constant
contact with the E-label reader. The E-label reader sends memory information to the dc
controller, which updates the information and sends it back to the E-label.

The dc controller instructs the E-label to read information when:

● the printe r is turned on.

● the top cover is closed.

● a command is sent from the video controller.

The dc controller instructs the E-label to write information when:

● a specified period occurs during printing.

● a command is sent from the video controller.

If the E-label reader fa ils to rea d or write information four times in a row, the dc controller notifies
the video controller that an abnormality exists in the imaging drum.
