Intermec EasyCoder 501 E – Installation & Operation Ed. 1
In the optional ribbon save print device, the label stop/black mark
sensor (LSS) is partially enclosed by two black plastic guide plates.
These have been added to prevent thin receiving media from getting
jammed when pushed forward by the rear drive roller at the time
when the printhead is lifted.
The guide plates can easily be removed for cleaning. First, pull the
upper guide straight out. Then, press the snap-lock of the lower
guide by means of a coin or screwdriver and lift the outer end free
before carefully pulling the guide plate out.
Both guide plates are provided with seemingly opaque, smooth
windows, which actually are transparent to the light of the LSS.
These windows must be kept clean from dust, stuck labels and
adhesive residue. Only use isopropyl alcohol for cleaning.
When putting back the guide plates, start with the lower one and
insert the two studs on the inner side into the corresponding holes in
the inner gable. Then press down the outer end so the snap-lock fi ts
into the slot in the outer gable.
The upper guide is threaded onto the beam of the LSS and connects
to the lower guide by means of a pin and a metallic snap-lock.
Do not use excessive force when removing or fi tting the guide
plates!
When needed, the rear rollers can be cleaned using a blotting paper
or soft cloth slightly moistened with isopropyl alcohol.
