DX-C400

[mmechura]

Hi all,
I have a DXC400 that stopped printing, the machine is calling for black drum and developer. The customer replaced the drum unit, developer units seem to be back ordered nationwide. Is there a way to "cheat" the machine to get it to work. I am not a Sharp tech but have been servicing Kyocera/Mita for almost 30 years. Any help is greatly appreciated, thanks.

Re: DX-C400

You can clear the developer counter in sin 24-5. Clearing the counter will not affect the currently recorded stir values, or image quality.

When you change the developer you'll want to clear the counter again, and stir (25-2). =^..^=

Thanks BC You are a wealth of knowledge and a huge help. Can you please tell me how to get into simulation on this machine. Thanks

Disable SNMP in the port or through 55-3 switch 9 bit 5.

His post actually makes sense, Blackcat; SNMP print service will halt all print jobs while the copier is displaying maintenance codes.

As an aside -- I've been doing testing with these machines after some helpful tips from other techs. My findings have been in line with what was explained to me, these little MXC/DXC boxes don't need developer changes. I have several new units (MXC312) out in the field that have gone through 2-3 drum changes and are still on the original developer. So far the savings have been pretty sweet.

Sorry,
I totally missed that connection.

It might be the withdrawal from the Meds he was on!

Re: DX-C400 scanning alignment

New issue, same machine. On the rear side of scanning/copying only in full color mode only the machine is not aligning the colors properly. There are examples attached. Any ideas? The issue is only the rightmost 1 7/8". In printing mode all colors are properly aligned. The examples originals are printed from this machine and the copies are scanned to this machine. Any help is greatly appreciated. Please detail your response as I am not too familiar with this machine. Thank you in advance.

Re: DX-C400

Are you using the ADF or OC (off the contact glass)?

If it's off the glass, it's got to be optical or image processing. Start by examining the optics for loose mirrors, lumpy grease on the scanner rails, missing or unseated glides (plastic contact surface on light source #1/#2 to the rail), too loose or too tight scan cable, cable over-wrapped on the drum, etc.

Most likely, when you move the scanner by hand you're going to find a rough spot in the motion 6 5/8" from the leading edge, and you'll have to determine why.

If it's through the ADF, you may have a drive problem that causes the original to shift at the trail edge. With these ADF's ... well they're jammomatics. The best place to start is to remove the mechanical section from the ADF body, and clean every rubber roller (not just the pickup, feed, and sep). That solves most of the problems with this ADF. It's a little tricky to disassemble: From below left there are four screws (two at front two at rear) that release a plastic block at front and rear. Once those are loose, the rest is self explanatory. =^..^=

Also simulation 26-38 can be adjusted to not stop you from copying when your maintenance lights come on.
