CHAPTER 5 ______
Maintaining Your Printer
The Microline 92 and 93 printers are virtually maintenance-
free so that you don't need a BSEE degree to keep them in
excellent condition
.
Although we have a few suggestions
that will help your printer, they are by no means mandatory
to perform.
-
Each time you change the ribbon, take a premoistened
towelette and wipe off the paper feed area below the platen
where paper lint may accumulate.
-
About every six months (if you have a steady hand) place a
small drop of 10/30 weight lubricating oil on the lower
carriage shaft. Then slide the printhead (after it has cooled
for at least five minutes) along the shaft to spread the drop
of oil evenly on the bar. Remember, just the smallest drop
will do
-
too much will cause all sorts of headaches. For
example, using too much oil or oiling more than the lower
carriage shaft could result in:
Blurry printing from oil on the ribbon or ribbon rollers.
Poor operation from oil on the microswitch or home
sensor.
Stained paper from oil on the platen, pressure roller or
pin tractor.
Poor printing from oil on the synchro belt, belt pulley
teeth or ribbon drive assembly.
So you can see, it's best to use the oil sparingly or have
your dealer assist you
.
Troubleshooting
Q. The paper does not advance. Why not?
A. If a tractor feed unit is installed, check to see if the
pins are properly engaged with the paper.
Q. Why is the paper lamp on?
A.
The printer is out of paper
.
If paper is correctly in-
serted and the light does not go out, contact your
dealer. The ROM memory check may have located
a fault.
