Cleaning the Label Stop Sensor

EasyCoder PX4i Bar Code Label Printer User's Guide (Fingerprint Version)
Never use any sharp tools for removing stuck labels. The
printhead and rollers are delicate.
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 the guides are
not clean, stuck labels or other objects may block the light beam.
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. 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.
