We have an epson aculaser c1900 which is telling us to replace the waste t-box. What does this mean?

this error refers to a misalignment of the carousel, i have one that randomly does it at the moment, i also have a replace black toner even though the toner is full, i'll get back to ya when i find a fix, the service manual says it can either be the 2nd motor, clutch or sensor, but in my case all three are working fine.

I don't know anything about this printer but look for a small switch where the waste box attaches to the printer. When you locate it press it in and if the "install waste box" goes out you simply have to devise some way to keep the switch pressed all the time. Try some super glue, or maybe a simple piece of paper folded up. Good luck.

transfer belt cleaner error
replace the transfer belt unit

ERROR CODE: E020
“SECONDARY TRANSFER VOLTAGE CONTACT/RELEASE PROBLEM”
Solution
�� Electric parts which can cause the trouble:
• Transfer Roller Pressure Solenoid (SL2)
• Transfer Roller Pressure Position Detection Sensor (PC7)
• Engine Board (PWB-A)

Sounds like the transfer roller or the fuser unit may be faulty. Look at the fuser to see if the roller surfaces are dirty. If so, replace the fuser.

the photoconductor unit may need replacing ? have you given your printer a service ? clean out all the dust from your unit making sure you dont touch the conductor unit do the best you can and try it again ok making sure the wast collector is empty too thanks

hi this solution has already been covered in full lengths. Epson c900 and c1900 are similar. have a look at my posting on this. photoconductor reseting by Labatt in this forum. read from the start.

I have a C1900 with an error "Service Req E021". I appreciate any help as to what this refers to please.

The Cleaner Pressure Flapper Solenoid it dead or dying. You can try moving it by hand to see if you can prolong it, but basically it needs a new one. Its a job for an engineer really.
