1.4.1 Installing and Replacing Roll Paper
Note:
Be sure to use roll paper that meets printer specifications. See Appendix B for details on the paper
specifications.
Do not use roll paper whose trailing end is glued to the roll paper core.
1.4.1.1 Installing Roll Paper
1. Make sure the host has not sent a printing command to the printer, and press the cover open
button to open the printer cover. If the printer cover does not open, a probable cause is that
the autocutter is locked. If this happens, refer to “Removing Jammed Paper” (page 1-7).
Figure 1-3 Cover open button
2. Load the roll paper.
Figure 1-4 Loading paper
Note:
When loading the roll paper, pay attention to the direction that the roll paper is fed out of the printer.

4. Tear off the leading edge of the roll paper using the manual cutter.
Figure 1-7 Tear off paper
1.4.1.2 Replacing Paper
Follow the procedure below to replace roll paper.
1. Open the printer cover, and remove the core of the previously used roll paper.
2. Insert the new roll paper following the procedure in “Installing Roll Paper” (page 1-6).
1.4.2 Removing Jammed Paper
CAUTION:
Do not touch the thermal head because it can be very hot after printing.
For handling the thermal head, refer to “Cleaning the Thermal Head” (page 1-8).
1. Turn the printer off and press the cover open button.
2. Remove jammed paper, reinstall the roll, and close the cover.
Rev. A Product Overview 1-7
If paper is caught in the cutter and you cannot open the printer cover
1. Open the cutter cover as shown in the illustration below.
2. 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 the illustration below.
3. Close the cutter cover.
4. Open the printer cover and remove the jammed paper.
1.4.3 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, methanol, or IPA).
Epson recommends cleaning the thermal head periodically (generally every 3 months) to
maintain receipt print quality.

1.4.4 Power Switch Cover
Install the power switch cover that comes with the TM-T88IV onto the printer to prevent
inadvertent changing of the power switch, to prevent tampering, and to improve the appearance
of the printer.
To reset the TM printer when the power switch cover is installed, insert a long, thin object (such
as the end of a paper clip) into the hole in the power switch cover and press the power switch.
