Paper Preheater Cleaning - Tektronix Phaser 360 Service Manual

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.
Heavier-weight, high-grade quality bond paper works best for this procedure.
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
supported.
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 user 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 absorbs and removes ink from the paper preheater.
4. The printer returns to the Clean menu.
Because of the higher temperatures involved, this function can also be used to
clean the drum surface of ink deposits caused by a contaminated wick on the
drum maintenance cartridge.
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 roller. This procedure requires the pick roller cleaning tray.
In the pick roller cleaning cycle, these events take place:
1.
The user starts the Clean: Media Tray Jams menu item.
2. The front panel prompts the user 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 user starts the cleaning cycle; the printer responds by rotating the
pick rollers eight times.
4. The printer prompts the user to remove the cleaning tray and returns
to the cleaning menu.
