This chapter provides specifications, safety compliance, options, available supplies, printing paper
and design, system configuration, related manuals, and servicing approach for the 4060 cut sheet
printer and supporting optional Large-Capacity Hopper (LCH) and Large-Capacity Stacker (LCS)
paper handlers.
The 4060 non-impact printer combines semiconductor laser optical technology and twocomponent dry development process technology to print on cut-sheet plain paper. Figure 1-1
illustrates an installed printer and the external large capacity paper handling options.

Model 4060 printer custom paper tray is user-installable, optional custom paper tray for the 4060
printer that is compatible and switchable with the standard printer paper tray. The custom paper
tray can hold up to 500 sheets (75g/m2) of free sized paper as listed in Table 1-13 specifications.

Paper Size Inches Millimeters
Minimum 4.7 x 7.2 120 x 182
Maximum 11.7 x 17 297 x 431.8
Paper size information for the custom tray is selectable. The custom tray also supports the
following standard media sizes: Letter, Legal, Ledger, Executive, A3, A4, A5, B4 and B5.
The printing speed from the custom tray is listed in Table 1-2 (measured on and after the second
page in continuous printing mode).
1-7. Printer Consumable Specifications
This section explains how the replacement rate is established for the printer consumables. The
4060 User Manual
procedures.
Table 1-14 lists the consumables and their respective replacement cycle specifications. Ensure that
consumables are replaced at the recommended intervals by monitoring the usage of the printer.
Consumable Item Replacement cycle
Toner 20,000 images for continuous printing, with 4% coverage for each bottle (average 18,000 images)
Developer 1,600 drum count for each bottle (160,000 images for continuous printing, average 114,000 images)
Drum 2,500 drum count (250,000 images for continuous printing, average 178,500 images)
Transfer Charger 2,500 drum count (250,000 images for continuous printing, average 178,500 images)
Fuser 3,000 page length count (approx. 300,000 images)
Cleaning Roller 40,000 images for continuous printing with 4% coverage (average 36,000 images)
Ozone Filter 3,200 drum count (320,000 images for continuous printing, average 228,000 images)

Notes supporting Table 1-14:
(1) All the values for replacement cycle shown above are based upon printing on A4 size
paper.

General Information
SERVICE MANUAL
(2) All the listed values are theoretical. The damage due to improper handling, maintenance,
papers, environments, and other uncontrollable occasions are not considered in these
values.
(3) All the values for replacement cycle/life shown above depends on printing usage’s and
conditions:
Drum Counts
•
: The drum counter will increment every 150 seconds (equals 100
images of A4 paper at continuous printing). This counter increments during
Warming-up, Intermittent printing and Auto-patrol sequence.
Calculation of the average printed images is based on 1/1.4 of continuous printing;
the combination of intermitted printing mode and continuous printing mode.
Page Length count
•
: The page length counter will increase after 100 simplex A4
images are stacked. On duplex printing the page length counter is incremented by
two.
For the Printer Pick Roller Kit and the LCH Pick Roller Kit, this counter always
increments as simplex printing. When another size paper is used, the counter
increments according to the Table 1-15 listed values.
