Printed images are faint.
Printed texts are blurred. If the machine is not used for an
extended period of time, ink on the

blurred printing just after printing is
started. The ink on the Print Drum (Cylinder) will
dry when the machine is not in use for an
extended period. Printing with dried ink will
produce light or faded copies.
Press the
key and make several
copies before making copies to be actually
used. Or use the “Idling Action”.
