Care of the C-Fax

There are no parts to be lubricated.
When a new roll of paper is fitted remove any paper scraps or dust from the paper
compartment. At this time also check and clean the rubber pressure roller if necessary. The
roller should only be cleaned with alcohol.
If a printed picture has vertical light stripes through it the most likely cause is dirt on the
print head. If this problem appears open the paper compartment and check the print head,
which is mounted on a horizontal metal bar at the top of the paper compartment. Near the
top of the print head (about 5mm above the line of black rubber) is a thin black line, this is
the thermal print line. Dirt on this print line causes the reduced print density. This should be
gently wiped clean with alcohol (methylated spirits or isopropyl alcohol) on a clean lint free
cloth or paper tissue.
Avoid excessive cleaning of the print head or the use of abrasive substances.
Print Line
This problem can be kept to a minimum by taking care when fitting paper rolls that the
outside layer of paper is clean and by not touching the print head.
Some brands of thermal paper leave behind a white chalky residue. If this builds up it can
cause printing problems. The easiest way to remove it is to run the edge of a finger nail
along the print line and scrape it clean. If the problem reoccurs we suggest trying a different
brand of paper.
