11 Troubleshooting and Recovery
Not every failure means that there is an error that cannot be cleared by the user himself. You will save time and
money by recognizing and fixing simple errors on your own. The following tips are meant to help you with this:
Hardware RESET:
Activated by unplugging and reconnecting the power supply after a short break. This
reinitializes the printer.
Symptom
Possible Cause
Remedy
The printer seems to be
printing, but the paper is not
blackened.
The printer only prints a few
characters in one line. If
more is entered, it stops
printing altogether.
Paper inserted incorrectly.
The power supply is not optimal.
Wrong printer settings
Insert paper correctly.
Use sufficiently sized power supply and short feed
lines. Check all connections for possible transfer
resistances. Since high peak currents occur with
thermal printers, even the smallest transfer
resistances can result in intolerable voltage drops. In
this case, no power supply would be strong enough.
Buffering with capacitors is possible, if the power
supply is only too weak by a small margin and large
capacitors (e.g. 4,700 µF; high switching capability)
are used.
The printer only prints a few
dots in one line.
The
printer
does
not
recognize black marks
Wrong label settings.
Check settings and change if required.
Black mark sensor is dirty.
Clean black mark sensor.
