Chapter 3 Maintenance & Disassembly
ADF Slip Adjustment
The ADF Slip Adjustment should be performed when a new ADF unit is installed to replace an old
ADF unit. This adjustment prevents the elongation of a read image. If this adjustment is not
performed, the ADF roller may slip during document feeding.
Okidata recommends performing this procedure every 75,000 pages (use the Total Printer Page
Count) or if scanned images are elongate.
Refer to Section 3.2 of this Service Handbook for installation instructions for the ADF unit ().
