Display Message
“Hardware Alarm”
To analyse failures much more easier, an extended failure report has been
implemented. The messages described below will only occur in “Hardware Alarm”
state.
If this message occures the printer must be repaired before switching on again.
Please take care about the fact that in “Hardware Alarm” state the power voltage is
switched off to avoid further damages. Please read also chapter 4.6 “Monitoring of
printhead”.
1. Display (Example)
Hardware alarm alternative display +000000 131 – – –
000002 xx 000482
2. Meaning of the Messages
Actual Position Head Clearance Head Temperature
Taskcontrol Desired Position
3. Legend
Actual Position Horizontal position of the printhead while error occurs
min. value = 0; (physical left margin)
max. value should be approx. 1730; (physical right margin)
Desired Position Horizontal Position the printhead tried to achieve
Head Clearance Relative printhead clearance while error occured
Head Temperature Current head temperature
Taskcontrol Error code (see item 6)
4. Interpretation of the example
Actual Position = 0 (left margin)
Desired Position = 482
Head Clearance = 131 (relative position)
Head Temperature = - - - (below range of measuring = head “cold”)
Task control
= 002 (horizontal task, motor accelerate)
5. Analysis
The Desired Position and the Actual Position should be identical or close together.
By moving the printhead the function of the horizontal timing belt can be tested
(value of Actual Position is changing). The value of the head clearance is always a
desired position since there is no response of actual head clearance. Default
standard = 18; AGA = rel. position; max. value = 131 (i.e. after Initializing resp. power
on).
Please analyse Task Control Code using the table on the next page.
