IBM PCjr

1. Set the printer's Power switch to Off.
2. Remove the print mechanism.
3. The resistances on the CNT connector should be
within the ranges hsted below.
4. Measure these resistances now.
Low Ohm
High Ohm
WERE YOU ABLE TO READ THE CORRECT
RESISTANCES?
NO The print mechanism is bad. Replace it. Repeat
the advanced test to ensure that the IBM PC
Compact printer is operating correctly.
