Factors Limiting Printing Start - Epson AcuLaser CX11 Service Manual

EPSON AcuLaser CX11/CX11F

FACTORS LIMITING PRINTING START

1 Cycle Down To keep the image density at target level.
2 Cycle Up To correct the toner density
3 Photoconductor Unit Parameter control according to the piece-to-piece variations
of Photoconductor.
4 New Toner Cartridge Filling toner -> Recovering from an Empty error
5 Prevention of color toner To prevent the color toner from concentrating to the left side
concentration in the developer, which may cause partly (right side on the
paper) missed printouts, after printing in black and white
continuously.
(By the rotary rotation while performing continuous black
and white printing, color toner, which is not used for the B/
W printing, is moved along the spiral of the Auger (The
Auger of the developer for colors do not rotate during black
and white printing). With the color toner concentrated to the
left side, color printing may result in missing the right side
image.)
Note *1: When the operation performed during the warm-up, the warm-up time becomes 74 seconds.
*2: The warm-up time is included. (After the cover is opened and closed, the normal warm-up operation is executed.)
TONER DUTY LIMITING VALUE
240% (to prevent paper from twisting around the FUSER ASSY)
NOTE: If it exceeds 240%, the engine (Mechanical Controller) forces a hard stop.
Table 1-28. Factors Limiting Printing Start
Purpose
When the number of printed copies (pages) becomes 20 (by both continuous or
intermittent printing) after performing the ADC, the printer performs another
ADC when the current job is finished.
1. The printer performs the ADC if the SENSOR HUM & TEMP detects that the
temperature and humidity in the printer are under the following conditions at
power-on or when returning from the low-power mode.
2. The SENSOR HUM & TEMP detects the temperature and humidity inside the
printer at power-on. The detected condition is compared to the condition
detected at the previous power-off, and if the difference is as shown below, the
printer performs the ADC.
The printer performs the ADC when replacing the Photoconductor unit with a new
one or used one.
The printer performs the ADC when replacing the Toner Cartridge with a new
one. (Not performed when replacing with a used one.)
1. When the printer have finished five B/W print jobs in a row, it rotates the
Augers of the three developers (C, M and Y) switching the rotary position to let
the color toner in the developers spread evenly.
2. When the printer is turned on for the first time after purchase, it does the same
operation as described above so that the toner spread evenly in the developers.
