Horizontal lines appear on the
printed paper.
• Impact can cause lines to appear on printed paper and
other malfunctions.
Protect the printer from impact at all times, especially
while it is printing.
• If lines appear on prints, turn the printer off, wait a few
moments, and then turn it back on again. Then, perform
the print job again.
