need more memory in the printer

Sounds like a driver problem. Some printers require eoj (end of job) character & will wait forever.
Do a test print (search internet on how to print status page- usually button press combo). If you get a printout, you know the print engine is good.
If the printer is able to parse text, then try sending an ascii test file & see if anything prints. This will tell you whether it's a comm issue or rendering issue.

There is probably nothing wrong with the printer, but it may not be be receiving all the dope it needs. Usually the printer needs a CR/LF signal at the end of the file to print. If it doesn't get that it will assume that it hasn't got all the file and will hang. This may be a setting in the application producing the file, or a setting on the printer itself (i.e needing either a full CR/LF signal or just one of these). Don't like the idea that it doesn't print its own test page though....

Go into the Job review mode and highlight the pending print job (note: it may be stuck in processing). You should then get the option to delete the job.

Make sure that the pending print job is also cleared from the network print queue. They can sit in the queue and be persistent on processing, even after you've cleared the copier. Clear the queue prior to deleting the job on the copier.

If this doesn't, disconnect the copier from your network and try the above steps again, then reboot the copier and reconnect it to your network.

If you're trying to print out Adobe-based web pages from the internet, this may be what's causing your copier to jam up. There's known coding anomalies with Adobe-embedded documents on web pages. Trying to directly print from the web page can stall or lock up the print process.

The service Manual says that if both the ready (Bulb) light and the exclamation light are both on it is a invalid engine
code /Invalid network code. But to clarify that you say they are both on and solid and not blinking. If they are you have a bad main board.
If they are blinking then the error is a Flushing /Resolution reduced error.
The cause is:
Printer is processing data or printing pages,but the resolution of a page in the current print job is reduced from 600 dots per inch (dpi) to 300 dpi to prevent a memory full error.
Solution is:
Wait until the ready light is displayed to print other jobs.
• Press and release the triangle button to cancel print job. It is the lower of the two buttons.
• Press and hold the traiangle button again to reset printer.
Hope this helps

Unplug printer cable.
turn off
turn back on and wait for READY
turn off
connect printer cable
turn on

If you don't print via a server,you can turn the iRC3200 off...then back on and that will clear the print jobs.
If after doing this it STILL has a traffic jam in the print que when trying to print the same document then stop sending THAT particular document as the document has a formatting issue and NOT the printer.
If you DO use a print server then you(or your I.T Professional) need to go to the server and clear the print jobs from the server.
