Lexmark C770

Lexmark C770 Printer Family

Color Laser printer for A4 / Letter paper size pages. Print speeds of up to 24ppm in black and colour at 1200 dpi engine resolution enhanced to "4800 Colour Quality".

The C750, C752, C760, C762 were based on the 5060 engine. The C770, C772, C780 and C782 are based on a revised 5061 engine. The C780 runs faster thanks to a faster 800MHz processor and a base of 256MB memory increasable to 768MB.

Models in the C770 family are:

  • C770n, 5061-100, base model 24ppm, 1200 dpi with 600 sheet input, 256MB RAM and Ethernet.
  • C770dn, 5061-110, base model plus automatic duplexing.
  • C770dtn base model with both duplexing and an extra 500 sheet tray.

The C772 Models are identical in speed and most aspects of the specification but there are more expansion options. These options include an outdoor media tray to handle signage and a banner tray allowing paper measuring 8.5" x 36" that can feed long cards through the machine.

C772n, 5061-300 base model with 600 sheet input, 256MB RAM and Ethernet as standard

C772dn, 5061-310 base model plus automatic duplexing.

The most significant direct competitor for the C770 was the HP Color LaserJet 3800 which had a slightly lower rated speed of 21ppm and a lower maximum paper capacity.

The C770 was succeeded by the C780, 5061-200 and C782, 5016-400. As the numbers suggest it's the same engine design but the consumables differ - so does the fuser.

Consumables:

As is normal with colour laser printers there are four colour print units. An Intermediate Transfer Unit (ITU) helps build the images. Toner is removed from the ITU by a second transfer roller. Waste toner is deposited in a separate bottle.

The fuser will also need replacing after 200,000 pages.

The printer will give the message "88.yy cartridge low" when sensors indicate toner is running low. The user manual recommends shaking the toner at this point to redistribute it and replacing the cartridge when the message persists or the print becomes faded.

The C770 can take standard and high yield cartridges

The C772 can additionally take extra high yield cartridges

C7702KH Black Toner Cartridge (10K Yield)

C7702CH Cyan Toner Cartridge (10K Yield)

C7702MH Magenta Toner Cartridge (10K Yield)

C7702YH Yellow Toner Cartridge (10K Yield)

Waste Toner Bottle:

Some toner is not used in the print process and goes to a waste container. The waste box needs replacing every so often. The message "82 Waste toner box nearly full" appears on the display to give the user an opportunity to order a new one. The message is given some time before the printer has to stop operating.

40X1756 Waste Toner Container for the C770, C772, C780 and C782 printer families.

The user manual gives the waste toner box as 10B3100 but that has been replaced by the 40X1756.

Instructions for changing the waste toner bottle are given in page 116 of the user manual.

Image Transfer Belt:

The image transfer unit builds the colour image to transfer to the page. The ITU is an electrostatic component and has a limited life of around 120,000 copies . Both the ITU and the secondary transfer roller need to be replaced when the message appears or if they are damaged by careless handling.

When the "83.yy ITU life warning message" appears on the display a new ITU is required.

There is a maintenance kit with both the ITU and the secondary transfer roller.

40X1788, Transfer Maintenance Kit (ITU with Transfer Roller, life 120,000 pages)

The user manual gives the ITU part number as 40X1680 but that has been superceded by 40X1788.

The same ITU is used by all the printers in the C770, C772 family but not by any others.

The ITU should only be placed on a clean flat surface. Never touch the surface of the ITU belt as that will damage it.

Fuser:

The fuser bonds toner to the paper. When a fuser unit fails symptoms are vertical marks on the page - and examination of the rollers inside the fuser usually shows marks corresponding with those on the page. The fuser is located in the lower right door assembly and is held by two latches at either side.

The same fuser is used by the C770n, C770dn and C770dtn and by the C772 family.

40X1651 115V Fuser - 40X1651

40X1832 Fuser Maintenance Kit (200 000 Pages) - 40X1832

The user manual gives the 220V fuser as 40X1666 but that has been replaced by the 40X1832.

The fuser can be equipped with a web-oiler - this gives a longer fuser life where very heavy page cover, plastic media or dual-web labels are frequently handled.

The operator panel displays 80 Fuser Maintenance when scheduled maintenance is required. Yield is 200,000 pages.

Instructions for removing the fuser and clearing paper jams are given on page 70 of the user manual.

After replacing the kit, the fuser maintenance count must be reset to zero to clear the message.
