[CQ] Sharp MX 2700

[Vesigoth]

This machine makes great looking black copies and prints, but when I make a color copy or print the color portion of the image is offset by about 1/4 inch, such that the image looks like a double image and the color balance is way off. If you've seen anything like this or can point me in the right direction please respond. Thanks

In your admin login, go to copy settings and do the calibration; then go to printer settings and do the same. If it's off by a quarter inch, the admin calibration may not be able to do it's thing. It may need a full calibration from the test commands.

check the drive gear on the primary transfer belt. they break across the drive pin. the gear is available as a spare or in the x1 kit

Actually the gear is in the y2 kit for this model. I would run the following in this order:
SIM 44-2, 50-22, 46-24 (x4) & 67-24 (x4).

SIM 44-2, 44-6, 44-26, then 50-22, 46-24 (x4) & 67-24 (x4).

Ive found running high density process control and half tone correction really helps for poor colors.

there isnt a y2 kit for this model. gear is in the x1 kit

I would first check the gear that Bill is talking about, if the gear is ok, try to run sim 50-22.

About the Y2 kit:

Secondary transfer kit 300K MX-270Y2
Secondary transfer belt x 1
Secondary transfer roller x 1
Secondary transfer idle gear x 1
Upper thermistor PA x 1
Primary transfer roller x 4
Belt drive gear x 1

don't want to labour a point but mx-270x2 contains transfer roller,drive idle gear and thermistor. This is from the handyguide for the uk. across the pond things must be different.

secondary transfer isn't going to cause this problem.

Thanks to all for your tips. I'll try them out and post my findings.

I am rather anal so I always run 50-22 (the way the book says) first. You really need to get the skew straight before moving on (though yes, technically you could run 44-6&26 first).

Before I even run the sims, I would verify the fixing roller tabs are down. It sort of sounds like a slipping transfer belt so you may want to check it out (you may not notice a slight shift in b/w). Then I would move on to checking skew.

BTW: This side of the pond has the Y1 for primary and Y2 for secondary.

You're right Bill, i checked the manual and the B2 + X1 + X2 kit in the UK = Y2 in north america.

My reason for running 44-6 first is in order for 50-22 to do a good job the machine needs to see good solids. If you got color density issues 50-22 could fail. Ive seen that on a BC320 were the drums were so old 50-22 could not complete because the solids were so poor the sensors could not see the patches. 99% of the time however it would not matter what what order you run them in.

After running Sim 50-22 I'm getting a Sub Magenta Front error 31. What does this refer to and how do I fix?

[Dark Helmet]

Try running Adj 6 in the SM getting your LSU and Drum skew corrected if there is any. Clean your procon sensors. Can you provide a sample of 64-5?

The copier is not able to line magenta up when performign image registration. This can be caused by poor magenta densitys, cracked transfer unit gear, dirty sensors.

I agree with bill that there is a gear in the x1 kit although maybe the kit is differently named in america? I have had this gear break around the pin also
