Maintenance
Interval and Cleaning products
Regular servicing and cleaning work is necessary for safe operation and high running
performance. The servicing intervals are dependent on the operation and ambient
conditions, daily operating times, and the print medium. Regularly clean the print head
and feed roller by removing any paper, adhesive, and ribbon residues using a dust-free
cloth and a neutral cleaning solution. Do not use any cleaning agents which could
damage or destroy the coating surfaces, labeling, display, type plates, electrical
components, etc. Avoid acidic or alkaline solutions. Ethanol and isopropyl alcohol (not
rubbing alcohol) are recommended for non-rubber parts. The rubber rollers and platens
are easily cleaned and rejuvenated using acetone. All rubber parts should be cleaned
when feeding operation becomes diminished.
Changing the separator roller
The separator (#9 Appendix C) is designed to be removable and replaceable when worn.
Also, this part might need to be changed when printing different materials ie. Tyvek
pouches vs. Tyvek lids. First, set the separator gap wide enough such that the separator is
not touching the feed wheel. Then, use a 3mm hex wrench to remove the separator screw.
Pull the old separator off and slide the new part on. Secure with the screw.
Cleaning the print head
1. Switch off the device.
2. Pull out the mains plug.
3. Remove material and ribbon.
4. Unscrew the two thumb screws on the print head module until the entire print head
module can be rotated clockwise on the contact shaft.
CAUTION! - The print head is a sensitive electronic component and can be easily
damaged by electrostatic charges. Therefore, discharge any bodily static electricity
before coming into contact with the print head by touching the base plate of the
printer. The print head does not need to be removed. Mark the position of the print
head on the contact shaft if it is not against the inside wall or outside stop.
5. Clean the print head using a dust-free cloth and a neutral cleaning solution.
CAUTION! Do not use any objects with sharp edges. Metal objects may never be
allowed to come into contact with the print head surface. They can damage the
individual elements of the print head, causing an un-repairable dead zone to form.
