Hi sir:
The error is in the 1) feeder 2) display of printing unit 3) or delivery???
You can do this first:
1) Perform a visual inspection : look for loose and broken wires, improperly seated connectors, loose or
broken wires
missing switch, missing jumpers. and so on.
Check for obviously damaged component(components burned or discolore due to overheating);
Dust + dirt + tear +wear
2) Reseating Boards and components:
Edge connectors are a common source of problems. Power down the system and remove the PC
boards. Examine the edge connector
for contamination and clean with contacts cleaner contacts. Reseat any loose components such as
scoketed ICs) . Reseat the
boards and power up.
3) Power supply checks:
Check the power supply for missing voltages and voltages out of spec. A digital multimieter DMM can
be necessary, as
voltage specifications are quite tight: logic supplies for example: must be within + 5% percent of
5Vdc. All the
multiple supplies and all must be checked.
4) Board swapping:
Board swapping involves the substitution of a known good board for a suspect one.
