HP policy on non-HP supplies
Hewlett-Packard Company cannot recommend the use of non-HP supplies, either new or
remanufactured. Because they are not HP products, HP cannot influence their design or control their
quality. Service or repairs required as a result of using a non-HP supply will not be covered under the
warranty.
When you insert a supply into the product, the product will inform you if the supply is not a genuine
HP supply. If you insert a genuine HP supply that has reached the low state from another HP device,
the product identifies the supply as non-HP. Simply return the supply to the original device to reactivate
the HP features and functionality.

When you install a non-HP print cartridge, Unauthorized appears on the control-panel display. In order
to print with this supply, you must press OK when you install this non-HP supply.
CAUTION: The product will not stop printing when this type of supply is empty. Damage to the product
could occur if the product prints with an empty non-HP print cartridge. See
warranty statement on page 319 and Print cartridge limited warranty statement on page 321.

Embedded Web server
This product is equipped with an embedded Web server (EWS), which provides access to information
about product and network activities. A Web server provides an environment in which Web programs
can run, much in the same way that an operating system, such as Windows, provides an environment
for programs to run on a computer. The output from these programs can then be displayed by a Web
browser, such as Microsoft Internet Explorer, Safari, or Netscape Navigator.
Features
An “embedded” Web server resides on a hardware device (such as an HP LaserJet product) or in
firmware, rather than as software that is loaded on a network server.
The advantage of an EWS is that it provides an interface to the product that anyone with a networkconnected product and computer can use. There is no special software to install or configure, but you
must have a supported Web browser on the computer. To gain access to the EWS, type the IP address
for the product in the address line of the browser. (To find the IP address, print a configuration page.
For more information about printing a configuration page, see
on page 237.)
NOTE: For Macintosh operating systems, you can use the EWS over a USB connection after installing
the Macintosh software included with the product.
The EWS allows you to view product and network status and manage printing functions from a computer.
With the EWS, you can complete the following tasks:
View product status information.
●
Determine the remaining life on all supplies and order new ones.
●
View and change part of the product configuration.
●
View and print some internal pages.
●

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 (LED)
●
Five mirrors and a lens
●
A CCD
●
Figure 4-2 Optical system
Scanner Glass
LED Lamp
600 ppi CCD
Lens
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 Fax Card as
a fax , or directing it to the computer as scanner output.
The image data collected is 600 pixels per inch (ppi). Each pixel has 8 bits for each of the three colors
(256 gray scale levels for each color), or a total of 24 bits per pixel (24-bit color).
72 Chapter 4 Theory of operation ENWW
Scanner operation
At power-on 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 cover is open. The paper path is incomplete if the ADF cover
is lifted from the glass.

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.
74 Chapter 4 Theory of operation ENWW
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 on 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 on 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.

Pickup/feed/delivery system
The pickup/feed/delivery system consists of several types of feed rollers and sensors. The DC controller
uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as
it passes through the printer. If media does not reach or pass each sensor within a specified time period,
the DC controller determines that a jam has occurred and alerts the formatter.
