Cleaning the Media Guides

EasyCoder PF4i User's Guide (IPL Version)
The label stop sensor, which controls the media feed, is partially
enclosed by two plastic guides. Light passes through slots
between the upper and lower part of the sensor. If these areas are
not clean, stuck labels or other objects may block the light beam
and the label stop sensor will not function.
If the printer starts to feed out labels in an unexpected way,
remove the guides as described below and check for anything
blocking the beam of light, such as dust, stuck labels, or adhesive
residue. If necessary, clean the guides using a cleaning card or a
soft cloth soaked with isopropyl alcohol. Do not use any other
type of chemicals.
Isopropyl alcohol [(CH-3)2CHOH; CAS 67-63-0] is a highly
flammable, moderately toxic, and mildly irritating substance.
To clean the Media Guides
1 Pull the upper guide straight out. (Upper part of print unit
omitted for better view.)
