1.5 Adjustment Items
The following adjustments must be made on this fax.
For the adjustment procedure, see
this Chapter 3. ADJUSTMENT.
Item When
CS LED lights-on duration When the SPCNT board, or the lithium battery, or the contact
adjustment sensor are replaced. Also, when the color or brightness of the copy
image or scan image is not normal.
Printhead position adjustment When the vertical lines shift during Bi-directional printing.
Automatic adjustment of CS LED lights-on duration
The CS LED lights-on duration, which can be adjusted via button operation, is also
adjusted automatically in the following cases:
• When power is turned ON then SRAM data is corrupted
When this product is shipped, after factory adjusment of the CS LED light-on
duration, the exposure control data is stored in SRAM. Because this data is preserved
by the Lithium battery even if the power supply is shut off, further adjustment is
unnecessary in almost all cases. When the machine’s power switch is turned on, the
data stored in SRAM is checked for correctness by Checksum, and if any data in
SRAM has been lost, adjustment of CS-LED lights-on duration is automatically
performed at that time. At first, a check is done for the presence/absence of a
document, and if there is no document, exposure control is performed automatically.
Exposure control data measured after this is stored in SRAM. When a document is
present, scanning is done in an error condition, an abnormal image is output, and the
contact sensor is aware that there is an abnormality.
