Print when cartridge is out
An Order Supplies message appears when a print cartridge is nearing the end of its life. A Replace
Supplies message appears when the print cartridge is depleted. To ensure optimal print quality,
HP recommends replacing a print cartridge when the Replace Supplies message displays. Print-quality
problems can occur when using a cartridge that is depleted, resulting in waste of print media and toner
from other cartridges. Replacing a print cartridge when the Replace Supplies message displays can
prevent this waste.
The Auto continue feature in HP ToolboxFX allows the product to continue using a print cartridge that
has reached the recommended replacement point.
WARNING! Using the Auto continue feature can result in unsatisfactory print quality.
WARNING! All print defects or supply failures incurred when an HP supply is used in cartridge-out-
override mode will not be considered to be defects in materials or workmanship in the supply under the
HP Print Cartridge Warranty Statement. For warranty information, see
statement on page 268.
You can enable or disable the Auto continue feature at any time, and you do not have to re-enable it
when you install a new print cartridge. When the Auto continue feature is turned on, the product
automatically continues printing when a print cartridge reaches the recommended replacement level. A
Replace Supplies Override In Use message displays while a print cartridge is being used in override
mode. When you replace the print cartridge with a new supply, the product deactivates the override
mode until another print cartridge reaches the recommended replacement level.

Latent-image formation stage
During the three steps that comprise this stage, a latent image is formed by applying a negative charge
to the photosensitive drum. You cannot see this image on the drum.
Step 1: primary charging
A high-voltage DC bias is applied to the primary charging roller, which is made of conductive rubber and
is in contact with the drum surface. As the roller moves across the drum, it applies the negative charge
to that surface.

Step 2: laser-beam exposure
The laser beam scans the photosensitive drum to neutralize the negative charge on portions of the drum
surface. An electrostatic latent image is formed where the negative charge is neutralized.

Developing stage
The developing cylinder comes in contact with the photosensitive drum and deposits toner on the
electrostatic latent image.
Laser beam
Step 3: development
Toner acquires a negative charge as a result of the friction from the developing cylinder rotating against
the developing blade. When the negatively-charged toner comes in contact with the drum, it adheres to
the electrostatic latent image. When the toner is on the drum, the image becomes visible.

Transfer stage
Step 4: primary transfer
The toner image on the photosensitive drum is transferred to the ITB. The DC positive bias is applied
to the primary transfer pad. The negatively charged toner transfers to the ITB from the drum surface.

DC bias
The toner image on the ITB is transferred to the print media. The DC positive bias is applied to the
secondary transfer roller. As the media passes between the secondary transfer roller and the ITB, the
toner image is transferred to the media.

Step 6: separation from the drum
The elasticity of the print media and the curvature of the ITB drive roller cause the media to separate
from the ITB.

Fusing stage
Until the fusing stage is complete, the image is not permanently affixed to the print media. The toner
can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet.
Step 7: fusing
The product uses an on-demand fixing method to fix the toner image onto the media. The toner image
is permanently affixed to the print media by the heat and pressure.

ITB cleaning stage
Step 8: ITB cleaning
The ITB cleaning roller and the cleaning brush are applied with the DC positive bias to charge the
residual toner positive. Because the primary transfer pad is also applied with the DC positive bias, the
positively-charged residual toner is reverse-transferred to the photosensitive drum from the ITB surface.

Drum cleaning stage
Most of the toner is removed from the photosensitive drum during the transfer stage. During the cleaning
stage, the residual, or waste, toner is cleared from the drum surface to prepare the surface for the next
latent-image formation.
Step 9: drum cleaning
The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and deposits
it in the waste-toner container. The drum is now clear, and is ready for the next image-formation process.

Removal and replacement strategy
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal procedures. Occasionally, notes and tips are
included to provide directions for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the component level.
Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its
original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides.
General cautions during removal and replacement
WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before attempting
to service the product. If this warning is not followed, severe injury can result, as well as damage to the
product. The power must be on for certain functional checks during troubleshooting. However, the power
supply should be disconnected during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten prefolds in the FFCs. You must ensure that all FFCs are fully seated in their connectors.
Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
Avoid pulling directly on wires to disconnect wire-harness connectors. Pull on the plastic body of a
connector whenever possible to avoid damaging the connector wires.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the thread pattern,
and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes
stripped, repair the screw-hole or replace the affected assembly.
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD
reminder when removing product parts. Always perform service work at an ESD-protected workstation
or mat. If an ESD workstation or mat is not available, ground yourself by touching the sheet-metal chassis
before touching an ESD-sensitive part.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.

Types of screws
WARNING! Ensure that components are replaced with the correct screw type. Using the incorrect
screw (for example, substituting a long screw for the correct shorter screw) can cause damage to the
product or interfere with product operation. Do not intermix screws that are removed from one
component with the screws that are removed from another component.
For a complete list of screw types and part numbers, see Parts and diagrams on page 229.
