5.2.2 Cleaning Page Function
There is a Charge Roller cleaning function within this printer, which can be executed by the user.
(1) While the printer is in off-line mode press both the left arrow and right arrow keys on the printer
operator panel for at least 2 seconds. The printer enters the cleaning mode.
(2) The LCD displays "CLEANING" on the upper line, and on the lower line, "MANUAL LETTER
REQUEST" is displayed. Characters will scroll one at a time from right to left. "LETTER" may be
replaced by "A4" depending on the default paper type selected in the menu. While the lower line
scrolls the message, the upper line will stay fixed.
When the above message appears on the LCD, the user can verify that the printer has entered the
cleaning mode.
(3) Insert a sheet of paper into the manual feed slot or press the "FORM FEED" button on the
printer.
(4) Toner attached to the image drum is transferred onto the inserted sheet, and the sheet is
ejected with the toner residue printed. While this process is going on, the LCD displays
"CLEANING PRINT" message.
(5) The printer returns to off-line mode.
