Introduction; Cleaning; General Cleaning; Cutter And Tear Bar - Printronix T3204 Maintenance Manual

Introduction

The printer requires very little maintenance. Periodically the printhead will
require cleaning, and the interior and exterior of the printer should be cleaned
as needed to prevent dust and dirt build-up. There is no requirement for
lubrication, and no need for any disassembly to perform the cleaning.
The mechanical adjustments should be performed only if there are print
quality or ribbon wrinkling problems. The ribbon setup is performed if ribbon
wrinkling and pull marks occur. The platen adjustment is used to correct print
quality problems such as uneven print shades.
These adjustments should be performed only by qualified trained
service personnel.

Cleaning

General Cleaning

A periodic cleaning should be performed on all rollers, guides and
assemblies. Low pressure air can be used to remove dust in the printer.
Isopropyl alcohol and a cotton swab can be used to clean any heavily soiled
areas. General cleaning will ensure that all parts are free of residue and will
not contribute to any printer malfunctions.
The media path and printhead should be cleaned each time a new roll of
media is installed in the printer.

Cutter and Tear Bar

Turn printer OFF and unplug AC power cord before cleaning the cutter
or tear bar.
Cutter blades and the tear bar can become gummed up from media backing
residue. These areas should be cleaned with Isopropyl alcohol when this
residue becomes noticeable.
