STEP 3: Reroll any loose paper coming from underneath the paper roll. Grasp the leading

edge of the paper and hold it toward the front of the printing unit, then close the transparent

cover. IMPORTANT: The leading edge of the paper must remain outside of the cover. See

Figure 3.

STEP 4: Confirm that the paper is feeding correctly by pressing the On/ADVANCE switch.

Check that the paper feeds smoothly, evenly, and remains properly centered within the

thermal head area. See Figure 4. When you are satisfied that the threading is correct, the

excess paper may be removed by using the built-in paper tearing edge.

REMOVING A PARTIAL ROLL OF PAPER In the event that a partially used roll of paper

requires removal, follow these simple steps:

STEP 1: Tear off any excess paper protruding from the print head, using the built-in paper

tearing edge.

STEP 2: Open the paper receptacle cover. Cut the paper web with scissors behind the lead-

in slot to the printer. The partially used roll may then be lifted out, and the paper in the print

head area ejected by activating the manual ON/ADVANCE switch until all of the paper has

passed through the print head area.

CUSTOMER SERVICING OPERATIONS With normal use, your printer should operate

properly for an extended period without requiring any service. The following service

operations are described because they might eventually be required and we want you to know

how to perform them correctly if they should become necessary.

Any additional maintenance or repairs to the printer will require laboratory equipment and

special components. Refer to the enclosed Warranty card for details.

SELF TEST A SELF-TEST mode has been built into your Alphacom 32 Printer to provide

a simple operational check. When placed in this mode the printer repeatedly prints a line of

the numeral "8" and a line of the numeral "1". The test mode is entered by pressing the OFF

button once while holding the ON/ADVANCE button down then releasing the

ON/ADVANCE button. To stop SELF-TEST, press the OFF button. To reset printer into

printing mode press ON/ADVANCE button.

PAPER JAMS Under normal operation there should be no problem with paper jamming in

the mechanism. In the event that small roll-ends of paper are removed or reinstalled in the

printer, care should be taken that the tightly curled paper does not wrap under the paper

stripper bar during the loading operation. If this occurs, the paper may begin to wrap around

the platen, until a thick roll of paper builds up between the pressure plate and the platen,

thereby stalling the printer. This is a difficult situation to remedy, since the platen will not

rotate backwards. It is best avoided by careful loading practices.

If a paper jam does occur, disconnect the power to the printer and try the following

technique to clear the jam.

1. Tear off and remove the paper roll from the paper compartment. Slice the paper layer by

layer with a very sharp knife and pull paper out. Do not cut the platen.

CAUTION: Never use or place tools between the thermal heads and the platen. The

probability of damage to the heads is very high under these circumstances.
