Bottom margin
adjustment
In order to improve the throughput, the printer minimizes the number of
print passes when printing on the bottom margin (bleed) in the borderless
printing. This may cause white area to appear on the bottom edge of the
borderless printout. In such case, use this adjustment to correct the printing
range on the bottom margin (bleed).
A bottom margin adjustment pattern is printed. Examine the printout
patterns and enter the value for best pattern to register the correction

Waste ink pad counter
The printer causes a maintenance error when the waste ink pad counter
reaches its maximum. Use this to reset the counter after replacing the
Waste Ink Pad. If you find the counter is close to the maximum during
servicing, carry out the pad replacement and the counter reset to avoid
the printer returned from the user due to the maintenance error.
After replacing the Waste Ink Pad, reset the counter to its default.
