CUTTER SPECIFICATIONS

Attributes: Consumable item that is replaced by the user, and it

is made of very hard steel, so the blade can easily be chipped.

Life: Can cut well over 2,000 pages, but the actual wear-

and-tear depends on the type and thickness of the paper used. The cutter life can be determined by manually using it to cut a piece of normal paper. If the cutter easily cuts the paper, it is OK. The cutter position is determined by the carriage cover position; see “Carriage Cover Height Adjustment” on page 139 and “Cutter Position Adjustment” on page 140 for more information.

1.3.3 Maintenance Errors

There are several consumable parts in the printer, and the printer employs separate counters to keep track of each one. The “Maintenance Req. 0100” message appears on the display to warn that the Waste Ink pads are about 99% full and need to be replaced soon.

The printer can continue to print even though the “Maintenance Req. 0100* message appears instead of the “Ready” or “Printing” message. However, when the waste ink counter determines the Waste Ink pads are 100% full, the “Service Req 00000100” message appears and the printer can no longer print.

To clear the Maintenance error, perform the following. Replace: The following seven items are need to be replaced.

- Waste Ink Pads (R/L)

- Pump Assembly

- Cap Assembly
