4.1 Overview

This chapter describes how to maintain the printer in order to always obtain the best performances from it.
In this chapter it is possible to find also some helps to test printer and to identify defective components using
Test & Diagnostic facilities.
First-Level maintenance is based at O.R.U. (Optimum Replaceable Unit).

4.2 Initial Inspection and Tools

When the printer presents a trouble, before proceeding to the service maintenance, an initial inspection must
be done. In fact, a problem in the printout often is due to a bad or wrong condition of the printer itself.
The parameters that must be previous checked are: set-up, cleaning, paper specification.
After that, if the problem remains, a troubleshooting session can be activated.
Requested Tools
• A Multimeter for resistance and voltage measurements.
• Soft Cloth

4.4 Cleaning

No preventive maintenance, on a schedule basis, is required.
Periodic cleaning will help to keep your printer in top condition.
Clean the printer as follows:
•
Every time that a maintenance operation has to be done or the ribbon cartridge has to be removed and
replaced by a new one, clean the lateral sides of the platen removing the paper dust. Use for this a soft
cloth or a little brush. This operation will be helpful for a correct behaviour of the edge sensor.
•
Use a neutral detergent or water solution on a soft cloth to clean dirt and grease from the cabinet of the
printer.
•
Do not use an abrasive cloth, alcohol, paint thinner or similar agents because they may cause
discoloration and scratching.
•
Be especially careful not do damage the electronic and mechanical components.
Check for the paper paths condition and to make sure they are correct.
If they are dirty (by paper residues or by ink), please clean them using a soft cloth.
