Function/[Setting]
To prevent the image density dropping
during continuous copying after a long
interval (this is caused by a sudden
increase of Q/M), VREF is changed by –
0.06 V every (100 X [SP2-974 value + 1])
prints. This correction is applied from
when the auto process control is done,
until "(the number of prints set in this SP
mode) X (SP2-974 value +1)" has been
made.
[0~20 / 0 / 1K copies]
Twenty ID patterns are made in an
interval of about 1 minute during a
continuous copy process just after
process control is completed. Image
density will be stabilized. However,
printing productivity will be reduced.
[0~1 / 0/ 1]

Displays the total operation time of the
development unit toner collection bottle.
[0~600 / 0 / 1 hour]
Need to replace soon: 580 hours
Need to replace now: 600 hours
After the bottle is replaced, reset the
value to 0 (zero) by pressing 0 and #
(Enter) keys.
Displays the total operation time of the
development toner suction motor.
[0~600 / 0 / 1 hour]
Need to replace soon: 570 hours
Need to replace now: 600 hours
After the motor is replaced, reset the
value to 0 (zero) by pressing 0 and #.
Adjusts how often toner is supplied
[0~3 / 0 / 1]
0: 1/1 (every print)
1: 1/2 (every 2 prints)
2: 1/3 (every 3 prints)
3: 1/4 (every 4 prints)
The operation of SP2968 now depends
on this SP mode setting. In this machine,
the Vref update interval has been
changed from "every 100 prints" to "every
[100X(SP2-974 value +1)] prints". For
example, if set to 1, toner is supplied
every 2 prints, and SP 2-974 value + 1 =
3.
