Chapter 3 — Troubleshooting and Maintaining the Printer
PF8d/PF8t Printers User’s Guide 33
Adjusting the Printhead Alignment
You can improve the print quality by adjusting the alignment
between the printhead and the platen roller.
• Turn the printhead adjusting screw counterclockwise or
clockwise to adjust the contact surface (alignment) between
the printhead and the platen roller.
Adjusting the Label Taken Sensor
The built-in label taken sensor can be enable to stop printing
until a printed label is removed from the printer’s output slot. As
long as the label taken sensor detects a label, the printer will be
busy and unable to receive data from the host.
When you are using the ESim protocol, note the following:
• The label taken sensor must be enabled using the manual
switch next to the sensor before it can be enabled or disabled
using ESim commands.
• When switching between peel-off, tear-off, and cut-off
operation, you must adjust the media feed in ESim by using a
j command.
If you are using InterDriver you can select a mode of operation
without issuing commands. You can select the following modes:
