development gamma error. dont really know how to solve this problem. iv changed the dev unit and few weeks later it came bk in with the same code. vac,d out the toner system but does not always work. this seems to be a common fault with these machines.

What does sp3-975 say?

- Upgrade Engine Firmware to V1.17 (SC387 can occur when color ratio is low).

- RTB 22 :

SYMPTOM

SC285, SC387, SC388, SC389 sometimes occur on machines that print primarily in B/W
mode (total color to B/W page ratio of 1:100), such as when using the machine primarily as
a fax machine.

CAUSE

Color development units are activated at power off/on, jam recovery and process control
(ID sensor pattern), which slightly charges and consumes the toner, but the units are
inactive and so toner is not replenished when printing out primarily in B/W mode (triggering
the SC).

Action Required

1. Set SP3-125-003 to a value of

2 to enable Job End & Non-use Self Check Mode.

Note:

This will instruct the machine to perform Auto Density Adjustment every 200
prints at the next job end (operation lasts approximately two to six minutes).
2. Set SP3-125-005 to a value of 0 (disable).

Note:

This will instruct the machine to ignore all environmental factors when performing

process control.
