Aficio 240W

[digicor]

I have a client that wont give up this machine to the spoils of the new age, that said, i have to go over there every other 3 weeks and clean the ID sensor,(just above the drum in the center) Ive replaced it three times only to find out cleaning it works, i re set the thing and its running for another round, My question is, is there a way around the sc401 with out changeing the Dv? By hard setting , or unchecking the density every when ever it does it? or extending the density check, Its been set , i cant remember, but its not pixels, "0" or "1" ive tried both, the book says the sc401 could be power supply sending over voltage, but i just clean it and it goes back to work.
Im assuming the DV is dusting up on it, its not over toning and the images look good, the drum itself has marks in it, but not right by ID sensor, it has 35k on it not really a lot.
but then again maybe this is a lot for this machine
Im looking to replace the machine , they are tied to some software thats running on there "win xp" that was expensive for plotting plans ,
so if there is one available you may know of please forward the info to me.
Thanks

When you cleaned the ID sensor, how did you do so? The recommended method is to use a soft cotton cloth moistened with clean water only. Use of anything else will result in either static on the surface that will attract either dust or toner, a cleaned film or clouded surface from etching of the surface by solvents.

i jsut wiped it with a dry cloth, nothing else, i did blow it with canned air once as well

Dry cloth will cause static.

[digicor]

ok i can re clean it with a damp cloth?

AS one who has not worked on wide formats but most other series,i know on my 60cpm b/w series that the drum mylar
gets hard from the exposure to toner and heat and if you can clean it use only warm water and a nice soft cloth..
if toner is slowly leaking onto the sensor,i have done this till i can change the seal/drum mylar

2208 Toner Supply Setting
001 Gain Sets the toner supply capacity for the job load.
[0~3/1/1]
0: H (Low)
1: M (Medium)
2: H (High)
3: HH (Very High)
002 Supply Pause Level Not Used
003 Toner Supply Mode Sets the toner supply mode.
0: Detect Mode
1: Fixed Mode
If the ID sensor is damaged and cannot be replaced
immediately, set this SP to .1.. Then, the customer can
continue to use the machine until a new ID sensor is
available. After you install a new ID sensor, reset the SP
to 0.


6.6.8 TONER DENSITY CONTROL
Overview
This machine uses an ID sensor to control:
• Toner density
• Toner near end detection
• Toner end detection
The machine uses the ratio of Vsg/Vsp to find the quantity of toner that must be
supplied to the drum.
To supply toner, the machine switches on the toner supply clutch to feed toner from
the toner cartridge to the development unit.
SP3103 (ID Sensor Output Display) shows the most recent values of Vsg and Vsp
that were stored in the NVRAM (Range: 0.00 ~ 5.00 V).
Supply Modes
There are two supply modes
• Detect Supply Mode
• Fixed Supply Mode
During normal operation, the machine uses detect supply mode.
Detect supply mode has two sub-modes (referred to as .tables.).
• Main table: Used during copying
• Length table: The machine switches to this table during copying if the length of
the copy becomes more than 1189 mm (46.8").
If an ID sensor problem occurs during the job, the machine stops at the end of the
job. The machine does not go into fixed supply mode automatically. The technician
must repair the machine. If the machine cannot be repaired, the technician must
put the machine into fixed supply mode with SP 2208 003.
In fixed supply mode, the machine supplies a set quantity of toner per page.
After the technician repairs the machine, the machine must be put back in detect
supply mode with SP 2208 003


Detect Supply Mode
Main Table
The machine uses this table from the start of the page until the length of the printed
page gets to 1189 mm (46.8").
The machine uses these two parameters to control the rate of toner supply:
• Vsg/Vsp
• The toner supply level set with SP2208 001
Vsp/Vsg Toner Supply Level (SP 2208 001)
L M H HH
Less than 10% None None None None
10% to 12% 10% 15% 20% 30%
More than 12% 30% 40% 50% 60%
Toner Near-End 100% 100% 100% 100%
Normally, Vsg/Vsp is less than 10%. So no toner is supplied during printing.
Length Table
If the page becomes longer than 1189 mm (46.8"), the machine changes to the
Length Table for the remaining part of the page.
But, if no toner was supplied before the start of the copy job, the quantity of toner
was sufficient at that time. Because of this, the machine does not change to the
Length Table.
The Length Table ignores the Vsp/Vsg ratio. Toner is supplied at a set rate. This
rate is controlled by the toner supply level set with SP 2208 001.
Length Table
Toner supply rate Toner Supply Level (SP 2208 001)
L M H HH
2% 4% 8% 15%
Under normal conditions (Vsp/Vsg less than 10%), no toner was supplied during
the first 1189 mm of the print. As a result, the developer does not contain much
toner. Because of this, the Length Table increases the toner supply rate from 0% to
2%, 4%, 8%, or 15%.

Good luck

Thank you very much for the insight

All good, just a FYI, Ratio makes the Plotbase controller and has a upgrade windows 7 box for a little less than 2grand. Its all preloaded and all is needed is to put it on their network and reconnect. You can make a quick $$ if your customer requires a upgrade. The rep is a located in your neck of the woods.
