Hi am new to the Canon, there are a few C1 machine that we look after, have a question about starter, how often should it be replaced, 500k is stated in the manual but i would assume that would be for Deveolper unit, i cannot imagine developer lasting that long.

Re: imagepress c1
unless u have major CQ Issues
--
wait until u change the Drum on this model /to do a full Starter change
if u change starter and leave in a old DRUM- U will be back the next day for E020 codes and cause more headaches
Idea-- get a MANUAL
part numbers for the Start Developer
IPQ-1 STARTER BLACK-------0401B001AA
IPQ-1 STARTER CYAN--------0402B001AA
IPQ-1 STARTER MAGENTA----0403B001AA
IPQ-1 STARTER YELLOW-----0404B001AA

Re: imagepress c1
Hi teckat thanks for your reply, i don't think i explained my question properly?
As i said i am new to Canon machines, previous techs have taken a hit and run approach to servicing these machines, one thing i want to introduce is to have a service schedule for these machines.
I have replaced the starters and do have the procedures on how to set them up, however as i stated in my original post, i question the 500k lifet stated in the manual, the developer units are not very large and i am guessing that the toner does contain a percentage of carrrier to replenish the Dev but even so i would be supprised if the developer lasted 500k even at 5-6% A4 (could be wrong,woulden't be the first time) let alone the 50-80 % A3 that the machine are doing.
What i am interested to find out is how often is the starter beining changed, is it infact lasting 500k.
ThanksComment

Re: imagepress c1
when u or customer perform the Auto Gradation/and or Fiery calibrations on a steady sch. u should have no issue with starter/ it is the Drum that goes first-
We have hundreds of these C1/C1+ printers in the Field/ the starter re-charges itself n these models/ it's not like the old CLC's-
we do not just replace the starter because of counter volume/ we replace it or replace the dev.units (units will depend on their volume) when we have to replace the DRUM/
as I stated if u replace the starter and the Drum surface is poor or getting old- u will promote un- necessary E020 codes
new dev units have starter inside them/
This equipment calculates the necessary volume of toner supply based on data collected in three different ways.
- Video Count (counts each document output when printing)
Estimates the amount of toner consumption from video counts data, and thus calculates the amount
actually consumed.
- Data from the Patch Image Scan Sensor (PS3) (performed sheet-to-sheet)
The patch image scan sensor measures toner image formed in the drum, and based on the data collected
the amount of toner supply is adjusted so that the over all density will get close to the target density.
- Data from the ATR Sensor (PS7) (detects every 8 document output of color print on A4 paper)
The ATR sensor detects the patch image density and the developer (toner and carrier) in the developing
assembly cylinder of each color. If the results fall outside of the target density range, toner supply target
will be either increased or decreased.
ACR Control (Auto Carrier Refresh Control)
This machine performs ACR control, which works for supplying developer and also discharging deteriorated
carrier, to increase the life of each developing unit.
The supplied developer is transported by the developer stirring screw in the developing unit.
After the waste toner is discharged by the developer stirring screw in the developing unit to the discharge mouth of the developing unit, it drops by its own weight when the developing rotary is rotating and will be collected to the waste toner bottle by the waste toner feeding screw located inside the rotary shaft.
The characteristic of the developer changes as the environment around the developing assembly changes, and it affects to the image density.
Therefore, the target contrast potential is determined by measuring the environment
(temperature / humidity) around the developing assembly with the environment sensor.**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

Re: imagepress c1
Thanks for the reply i do appreciate your time, as i stated i do get that the dev is constantly being replenished but do question it 500k life.
You said that you replace starters with drum, looking at the replacement schedule do you replace starters with every drum replacement or at the 4th drum replace dev units. (based on 125K drum life)
I am not having any specific problem or errors (except one that is having yellow registration problems), but am looking at it from a servicing point of view, as i said in the past there was no real service strategy with these machine, tech would fix problem and move on, my aim is to try to improve performance and reliability by having a regular service procedure set up.
We don't have a lot out there, but they have been a bit of a pain lately.
Also with drum i have seen estimated life figures of 150K (which is what we have been using) and 125K what do you replace at.Comment

Re: imagepress c1
Drum replacement all depends on customer volume / print coverage / copy quality/ error codes related to DRUM/ enviorment / there are no set standards to follow/
I don't pay attention to numbers/ numbers are for salespeople to sell a product>
500,000 is just a number used by Canon/ as an estimate in normal conditions/
in 25yrs working on Canon's - never seen a normal location
all of Canon numbers are based on 5/6% coverage of black text on letter size paper
this is what 6% looks like
