Cleaning the Drive Roller
WĂAĂRĂNĂIĂNĂG The drive roller cleaning procedure should be performed only
by HP trained personnel: otherwise personal injury may occur.
If ink is spilled on the drive roller, remove the ink. Due to the ink’s
reflectance, ink on the roller can disrupt the Printer’s edge-sensing function.
To remove any ink from the roller, perform the following procedure:
1 Make sure the printer is switched OFF from the power switch on the
back of the printer and not from the standby button on the front of the
printer.
2 Hold the UP and ENTER keys down and switch the printer ON. Wait
until the message “Status/Initializing” is displayed on the front-panel
before releasing the UP and ENTER keys.
3 Once the message “Status/Ready” is displayed on the front-panel, press
the Enter key.
4 Use the Arrow keys to scroll to the “Utilities” menu display and press
the Enter button. Make sure that you are in the Full menu mode
because otherwise you will not be able to access the “Service Tests”
submenu.
5 Use the Arrow keys to scroll to the “Service Tests” menu display and
press the Enter button.
6 Use the Arrow keys to scroll to the “Diagnostics” menu display and
press the Enter button.
7 Using the Up Arrow button, scroll to reach the following display and
press Enter:

8 The “Unload Media” message is displayed on the front-panel. Remove
the media (if loaded).
9 The “Move Roller” message is displayed on the front-panel. Use the Up
Arrow to rotate the drive roller clockwise and the Down Arrow to
rotate the drive roller counter-clockwise.
10 Open the window and apply any common household cleaning solution
(water based only) to a soft, lint-free rag and apply it to the drive roller
surface while it is rotating. Thoroughly clean the roller surface. Also
make sure that you clean the mark encoder on the left side of the driver
roller.
11 Press Previous when you have completed the cleaning procedure. The
“D1500 Done” message is displayed on the front-panel.
