I/U, Imaging Unit.
What do you mean?
Drum?
Please explain more.. -
Are you a technician?
It's a $2000 drum and I wouldn't recommend removing it if you're not sure of what you're doing. It's a really expensive mistake to make. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

The drum on this copier is rated for 3 million copies and if you are having a copy quality issue I would certainly start with the cheapest items first like corona rebuilds and other PM items. Have you opened up the right door of the copier & removed the developer unit so you can see the condition of the drum? It is behind a metal plate that comes off with one screw & unplug the connector & pulls right out. If you want to remove the Process unit (imaging unit) first take out the dv unit , then disconnect the toner hopper unit. This gives you access to the coronas and the process unit area. The dissassembly is described very thouroughly in the service manual. but the other posts are correct----ONE SCRATCH & YOU ARE DONE!. Do not attempt this dissassembly without reading the manual 1st. The dissasembly is not that hard if you know what you are doing but if its your 1st time you can make simple mistakes & cause a lot of damage. Good luck!sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

yes I'm a tech, but I work mostly on Konica minolta macines. I had a customer call and told my sec. that they needed the I/U replaced. I thought that it would by a drum in that large of a machine. Can anyone send me the replacement instructions for the drum.
ThanksComment

What you need if you are going to attempt this is the service manual. But I;m curious as to why the customer feels they need that expensive drum. Do a service call & remove the dv unit ( 1 screw and remove metal plate inside door on right side of machine ) Then inspect drum visually. Might just need drum blade or PM . What is the meter on this copier? Is drum scratched or pitted? Who told customer they needed that unit? Post a pic of the copy quality problem here & I can point you in the right direction on this repair.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Lines on the copyComment

If gray or black lines sounds like drum cleaning blade & a PM needed but also check fuser rollers. White lines - rebuild coronas & also check developer cylinder coating. Hope this was helpful.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Another question.
Are they printing to the machine?
You can check internal prints from service mode> Type PG4
To verifly if its internal prints. If everything checks well then proceed to check the scanning area which is the reader unit.
Check the optics, make sure there clean and the copy board glass, make sure its clean as well.Comment

Points to Note When Handling the Photosensitive Drum
The machine’s photosensitive drum is made of high-sensitivity amorphous
silicon, and its sensitivity can start to deteriorate depending on how and
where it is placed, requiring the following:
1. Whenever the process unit is removed from the machine or the photosensitive
drum is removed from the process unit, be sure to protect the
photosensitive drum against light. Use the photosensitive drum protective
sheet or wrap six or more sheets of A3 or larger copy paper.
2. Do not place the process unit or the photosensitive drum in an area subject
to the direct rays of the sun.
3. Do not place the process unit or the photosensitive drum in an area subject
to high or low temperature or humidity or where temperature or humidity
tend to fluctuate rapidly.
4. Do not place the process unit or the photosensitive drum in an area subject
to dust, ammonium gas, or organic solvent/gas.
The foregoing requirements commonly apply to all photosensitive drums.

Once you done some diagnosis, come on back and post the samples.
Depending on the appearance of the sample copies:
1) Dirty optics can cause lines. If you can print an internal report that will help narrow down if it's optical or not.
2) Corona wires are a regular maintenance item, and can cause a form of "lines". Fuzzy lines in the feed direction, as opposed to sharp lines from optics or drum cleaning.
3) I agree with the comments about drum cleaning. The plate blade is supposed to be reversable, but by the time the first side fails it's so dried out that you can't use the second side. The white writing on the blade should always be toward the drum when "flipping" the blade over. And be sure to prime it manually before inserting the imaging unit back into the machine.
Leave the drum safely in the machine until you've looked at these items. Most likely, the customer doesn't have a clue what an "imaging unit" is, and is just spouting something they heard from a printer service call.
Please don't be insulted by our cautionary comments. I think we've all had to explain what happened when we f***ed up a $2000 drum. Do yourself a favor and learn from our mistakes. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
