printer. See "Transport-Auto Cutter Assembly" in the "Disassembly" chapter.

♦ Guide Wheel
♦ Pins for Shear Plate

CLEANING THE PRINTER

Remove paper dust periodically by using a vacuum cleaner or air compressor.
Caution: Do not use alcohol or petroleum-based chemicals to clean the printer

MAKING ADJUSTMENTS

The adjustments described in this section are required only to correct Printhead
drag or print quality flaws.
If the print density on a print sample is consistent from left to right and top to
bottom, and the Printhead does not drag, no adjustment is necessary. If the
Printhead drags, the gap may be too narrow. Increase the gap in order to get the
proper air gap of .012 inch on both left and right sides.
After a period of use, the Feed Roll Shaft may wear down to a point where
adjusting the gap will not correct the print problem. In this case, the Feed Roll
Shaft needs to be replaced. The Feed Roll Shaft also needs to be replaced when
it is cracked or "weather checked." Refer to "Replacing the Feed Roll Shaft"
later in this chapter.
Note: Any time the Feed Roll Shaft is replaced, the bearings on either end
When: every six months or 100,000 cycles
When: every six months or 100,000 cycles
as these will damage the plastic parts. The Carriage Rack is
particularly sensitive and will be permanently damaged if exposed to
these chemicals. Take special care not to get the cleaner on any
electronic components.
must also be replaced.
Check the Platen Air Gap and readjust it if necessary. See "Adjusting
the Platen Parallel to the Printhead" and "Adjusting the Platen Air
Gap" later in this chapter.
