3.1 Required Adjustments
The table from the following page lists the required adjustments depending upon the parts being repaired or
replaced. Find the part(s) you removed or replaced, and check which adjustment(s) must be carried out.
After all required adjustments are complete, use the “Final check pattern print” function
to print all adjustment patterns for final check. If you find a problem with the printout
patterns, carry out the adjustment again.
When replacing the Main Board and the Printer Mechanism (Frame Base Assy) at the
same time, the adjustment should be made after performing the initial setting.
In this manual, the product name is abbreviated to such as “WP-5620 series”, however,
the last digit of the actual name may differ. Identify your product with the first three
digits and refer to the appropriate sections in this manual.
The table items and marks used in the “Required Adjustment List” provided on the
following pages have the following meanings.
• “O” indicates that the adjustment must be carried out.
• “---” indicates that the adjustment is not required.
• The “Mechanism Adjustment” should be performed just after reinstalling or
reassembling the part or unit. (See "Table 3-1 Required Adjustment List (Mechanism
adjustment) (p52)".)
• The “Adjustments using the Adjustment Program” need to be performed after
reassembling the printer completely. (See "Table 3-2 Required Adjustment List
(Adjustment using the Adjustment Program) (p54)".)
If you have removed or replaced multiple parts, make sure to check the required
adjustments for the all parts. And when multiple adjustments must be carried out, be
sure to carry them out in the order given in the “Priority” row.
