Ignore Printhead
To allow operating the printer without plugged in printhead (no printhead control, no
temperature control) a special “Ignore Printhead” mode was implemented. You can
achieve it by pressing keys 1, 2 and Setup during power on procedure. Further also
Show-function will be set to on. This is suitable for enhanced test purposes.
No clocks from timing strip – check whether the strip positiones in
the barrier
– check whether the strip is damaged or
lose
– check whether the barrier is plugged in
correctly
– substitute the sensor (light barrier)
Missing clocks from timing strip intermit-
tent (printout is moving horizontally until
carriage blocks on any side panel) – substitute head adapter cable; replace
it with level C
– substitute light barrier (horizontal sen-
sor)
– check ,,noisy“ environment: interface,
main controller, CR-motor
Reason Solution
AGA Flag defective or missing Substitute AGA flag on indicator axle
System not adjusted Switch printer on without paper loaded
Phenomena Countermeasure
AGA shows correct value (Show func-
tion) but the printout is not correct or the
printer prints but no impact on the paper – check whether the white damper on
each side are hanging / blocking
– check whether the excentric wheels on
both sides are mounted parallely
– check basic head distance
Reason Solution
Tractor drive does not engage – check mechanic of tractor 1/2 drive
