How to clean head for Tm 111 - Epson TM88II Thermal Printer

If the gaskets come with a coating of sealant, do not use any extra.. MAKE SURE the gasket surfaces are FLAT, CLEAN (with sandpaper/machining/wire brushing..etc.. and clean with brake cleaner and then acetone... If the surfaces(head and block) are smooth, defect free and you use the proper torque sequence and settings (+10%), you should not have a problem..BUT, here is what I use..

did you try the basics cleaning heads , running test setup for the dot matrix printout out , changing ink sometimes ne packages sold are garbage.

I found something on amazon. take a look: Amazon com john deere 111 manual I hope I have helped. Cheers

the chances of cleaning a thermal print head is slim.. but you can try to clean it with alcohor ... if it's scratch or damage, cleaning it won't help much...

Plain old isopropyl works perfectly.

Hello sir; You do need to clean print head with alcohal.

The following is from the Epson Users Manual:
Troubleshooting
No lights on the control panel
Check the power supply cable connections and the power outlet.
ERROR LED on (not flashing) with no printing
If PAPER OUT is on, the roll paper is not installed or is near the end.
If PAPER OUT is off, the printer cover is not closed properly.
ERROR LED flashing with no printing (and no paper jam)
Printing stops if the head overheats and resumes automatically when it cools.
If overheating is not the cause, turn the printer off, and after 10 seconds, back on.
Removing Jammed Paper
CAUTION:
Do not touch the thermal head because it can be very hot after printing.
1. Turn the printer off and press the cover open button.
2. Remove jammed paper, reinstall the roll, and close the cover.
3. If paper is caught in the cutter and you cannot open the printer cover, open
the cutter cover as shown in illustration J.
4. Turn the knob until you see a triangle in the opening. This returns the cutter
blade to the normal position. There is a label near the cutter to assist you. See
illustration K.
5. Close the cutter cover.
6. Open the printer cover and remove the jammed paper.
Cleaning the Thermal Head
CAUTION:
After printing, the thermal head can be very hot. Be careful not to touch it and
to let it cool before you clean it. Do not damage the thermal head by touching
it with your fingers or any hard object.
Turn off the printer, open the printer cover, and clean the thermal elements of the
thermal head with a cotton swab moistened with an alcohol solvent (ethanol, or
IPA).
Epson recommends cleaning the thermal head periodically (generally every
3 months) to maintain receipt print quality.

It sounds like your print head is overheating. Clean as instructed above.

How do you cleaned the printer heads? Did you cleaned it manually by wiping a cloth? You should not have to, because the screw and bolts will relocated and not fit to their original position or lost-threaded. You must use the tools of epson for cleaning heads and sharpening the printer output. Or just the download some printer tools for Epson TM J2100

no you don't. Just keep the most recent version.

Never use tape head cleaners, I suggest just use new blank tape and I recommend TDK minidv tapes, new tapes already serves as video head cleaner. If the problem is still there, manual cleaning is needed or it is possible that your video head is worn out already, you need profix then.
