Tab quality is as important as mail piece quality. Poor
quality tabs and mail pieces take longer to run, jam
often and produce poor results. Only genuine
Formax brand tabs are 100% guaranteed to run on
Formax Tabbers. Imitation tabs can be run on Formax
Tabbers, but are not guaranteed to run problem-free.
The FD 280 depends on a smooth flow of both tabs
and mail pieces. This flow is monitored by a set of
sensors and a microprocessor. As with most
microprocessor-controlled machines, the FD 280
needs a few seconds to get itself ready to run. When
you turn the power on, the FD 280 takes 5 seconds to
boot up. During this time the tab ready light flashes
and the control panel is inoperative.
Signals from sensors and the encoder are fed to the
microprocessor which monitors
the length of pieces
fed and calculates the average length of the piece.
Without correct measuring, the FD 280 will not tab.
The FD 280
’s sensors work like all other electric eyes.
When an object breaks the beam of light (the
SENSOR BEAM) between them, an electrical signal
is generated. It is imperative that this SENSOR
BEAM PATH be maintained in its proper condition
and alignment at all times.
Debris and stray tabs can become caught in the
paper path and sensor beam. Rough, careless
handling of the FD 280 can cause the sensors to
become mis-aligned. Both of these conditions must
be prevented. The FD 280 requires periodic cleaning
and reasonable handling. Paper dust build-up or
abuse will bring the successful operation of the FD
280 to an end. Take care of your FD 280 by following
the set up, operation and maintenance instructions in
this manual.
