Change the door switches. The laser power goes through them, it could be you have a slightly fritzing switch.

Key counter management needs to be enabled in user tools. Might take a bit of faffing with to get the right settings. There may also be a couple of SP modes to change, it should tell you in the...

Have you also fit torque limiters?

Solutions from service manual:

1. Check if the paper transfer roller unit is overloaded (foreign objects in the unit, bearing locked or stuck).
2. Check the connector of the PTR motor and the...

Not sure on the fuser, never tried it. I carry the M9550127 printer PCU and fit it to the copiers, you just swap the front and back plates and the TD sensor harness over. Never tried fitting an...

Is it SCC or CSS? If it's CSS I've seen this before, it's an SP mode. I'll have a look and see if I can find out what it is.

Is it a 4510 equipped with a HDD? Could be the spool data is getting corrupted due to a duff drive or RAM.

Was it a new controller? If not, the serial number from the old machine will be in there. Go to 5811 in factory SP and input the correct serial number.

Have you tried using the MX record on port 25 with no authentication? Input the customer's domain at mxtoolbox.com, it will come back with something like companyname-co-uk.mail.protection.outlook.com.

I've had the main motor shred due to developer contamination a few times. I've replaced the main motor, the PCU drive bracket and the PCU if it is leaking. D120 1027 for the bracket, AX060402 for the...

Drop the firmware zip on an SD card, stick it in the side of the panel, boot into recovery mode (hold EX1 and EX3 on power up, switch to EX1 and EX2 when the display shows the first image), select...

Are the feed heads swappable between trays 2 and 3? Might be an idea to try.

Tis the SD card / romdata method. FWU files should be placed in a folder called romdata on the root of a blank, non-HC SD card of a capacity ideally less than 1GB or partitioned down. Stick it in...

Are you sure it's an E-24? I didn't think the little E-2x Fiery's had CD drives. The E-44 does.

I have one of these, it's very good when fitted with an SSD.

Depends how you are doing it. If it's died completely, you'll have to use the USB flash method, which is dip switch 1 on.

Pretty sure switching off 5895 will get it's GW controller working again, but I'll check.

On the serial number sticker on the back of the machine, there will be an engine number, i.e. B039. Can we have that so we can get the proper model number please.

It hasn't had the slower fusing sleeve installed in it has it?

It does indeed, you just need to change the front and rear plates around and the TD sensor harness.

Are you using Ricoh toner? Mine last between 200-250k and we use M9550127.

Also, the green earth wire on the PTR assembly can break causing SC204.

Do you have a spare side door to try? The levers that lock the door shut have a shaft running through them which twists and causes this fault. The back of the door at the top being slightly stuck out...

I don't think any amount of tray heaters or dehumidifiers will sort this, especially as it is in an entrance hall. There's no way to regulate the environment, that's one thing copiers need, constant...
