10.2 Thermal Printer Card
Decline in print quality, voids or drop out areas in bar codes and/or graphics may indicate
that the print head is dirty and needs to be cleaned. The necessary cleaning materials can
be purchased through Microcom Corporation by contacting your sales representative and
ordering the Cleaning Kit, part # 040005-0000. The print head should be cleaned after every
roll of media or after every 512 feet (3200 tag which is a typical stack of tag or fanfold
media).
A thermal printer card is the quickest and easiest way to clean the print head, drive roller,
and peel edge all at the same time. Follow the steps below for the proper cleaning
procedure.
1. Remove any installed media.
2. Dampen both sides on one end, of the cleaning card with isopropyl alcohol.
3. Push the Head Release Levers towards the center of the printer and insert the card
into the front of the printer between the print head and the drive roller (See Figure
20).
4. Continue inserting the card until you feel resistance; close the head assembly so that
it latches in place.
5. Using both hands, slowly pull the card out of the printer at a 45º down angle (See
Figure 21).
6. Repeat as necessary
7. Reinstall media.
Thermal cleaning cards should not be used more than three times each. Extremely dirty
cards should be disposed of immediately.
CAUTION: Never touch or clean the print head with any abrasive
solvents and/or with any metal or sharp object.
