Paper preheater cleaning

Pick roller cleaning

This is a customer-initiated cleaning procedure, selected through the front panel
cleaning menu Clean: Ink Smears. The purpose of this cleaning item is to
clean ink out of the paper pre-heater that may have been deposited there. Ink
can be deposited in the paper pre-heater if a sheet of paper with ink on it was
rerun through the printer in an attempt at two-sided printing, which is not
allowed.
Ink can also be deposited if a jammed print, with ink on it, was pulled
backwards through the paper preheater. In the paper preheater clean cycle,
these events take place:
1. The customer starts the Clean: Ink Smears menu item.
2. The printer overheats the paper preheater to 110
trapped inside the paper preheater. Ordinarily the paper preheater
runs at temperatures of between 90 and 95
transparency film printing.
3.
The printer picks and passes 10 sheets of paper through the print path.
Each sheet attracts and removes ink from the paper preheater.
4. The printer returns to the Clean menu.
This is a customer-initiated cleaning procedure, selected through the front panel
cleaning menu Clean: Media Tray Jams. The purpose of this cleaning item
is to clean the pick pollers. This procedure requires the pick roller cleaning tray.
In the pick roller cleaning cycle, these events take place:
1. The customer starts the Clean: Media Tray Jams menu item.
2.
The front panel prompts the customer to install the cleaning tray in the
paper tray. (The user must remove all media from the paper tray and
also soak the cleaning tray's sponge with alcohol.)
3. The customer starts the cleaning cycle; the printer responds by
rotating the pick rollers eight times.
4. The printer prompts the customer to remove the cleaning tray and
returns to the cleaning menu.
