Description of problem
This problem is often caused by the ink soaking into the paper, making the
lines blurr
ed and fuzzy. This could be because of the humidity in the air.

emperature, humidity) are suitable
for high-quality printing.
2 Make sure that the p
aper type selected in the Front Panel is the same as
the paper type loaded into the Printer.
