I'm having a similar problem. So far my solution has been to disconnect the 3330 from power for a longer period (> 30min.) and then switch it back on again. After the self-test everything appears to be ok again. I've got no idea why, but this seems to work (for now)

The "scanner warming up" error is usually caused by dirty glass or mirrors in the scanner assembly. Here is a link to a step by step guide that tells how to open the scanner unit and clean the optics to clear the error.
ISSUE: A Scanner Bulb Error message is received as a result of the HP LaserJet 3300mfp series product scanner's inability to find the home reference point. SOLUTION: Perform the following steps to walk the scan assembly from the home base and resolve the issue.
1. Remove and replace the power cord from the unit. 2. Wait approximately 35 seconds for the scanning assembly to "walk out" and then quickly remove the plug again. 3. Repeat steps 1 and 2, three to four times until the head moves approximately 1 inch away from its normal resting place. 4. Replace the plug and let the product fully finish the boot cycle.
If this does not resolve the issue or the issue returns, upgrading the product firmware may help. The firmware upgrade can be found at the HP Web site Downloads, Drivers, and Notifications page .
From what you described it sounds like you need to get the "scanner assembly" replaced. The bulb is probably bad and won't come on to full power. Not knowing what kind of printer you have, probably won't change the fix. If you can look at the event log you may be able to see an error code which could make it a definite scanner assembly replacement. If you want to throw money at this unknown printer, get a tech to look at it and give you an estimate.
You are correct with your diagnostics, he problem is caused by dirty optics. The mirrors in the scanner have dust, lint or smoke on them. When the scanner powers up it tries to calibrate itself and waits for the bulb to warm up so the light output gets to a certain level. With the dirty optics the scanner never gets enough light so it thinks the scanner is still warming up and so it waits for the light to get brighter. After a few minutes of waiting and not getting the correct level of light it gives the power off message. We have a dis-assembly and cleaning guide with step by step instructions posted on our web site at: http://www.ccl-la.com/blog/index.php/category/printer-repair/hp-printer-repair/ This procedure takes about 30 minutes to complete but it should et you back going again.
I hope this helps, If so please rate our solution.
There are actually some certain meaning on the red light and green light showing different information to user. The summaries are: 1) Green On, Red Off = Printer Ready. 2) Green Fast-Flashing, Red Fast-Flashing = Printer warm up. 3) Green Fast-Flashing, Red Off = Printer off-line. 4) Green Slow-Flashing, Red Off = Processing Data. 5) Green Off, Red On = Cover Opened, Toner Empty or Developer Unit / Drum unit missing. 6) Green Off, Red Fast-Flashing = Paper Jam or waiting for jam reset. 7) Green Off, Red Slow-Flashing = Paper Empty or Paper tray is not inserted. 8) Green Off, Red Off = Printer power is off. 9) Green Very-Slow-Flashing, Red Off = Printer in sleep mode. 10) Green (any condition above), Red Slow-Flashing = Toner low or paper empty.
So what is your printer condition? Better know what is going on your printer so can solve the problem.
I found this solution at HP website. It worked for me. Good luck!

1 = dark find 2 = LMW temp find 3 = bulb warm up from off 4 = bulb warm up from coarse 5 = cal label find 6 = doc original find 7 = LMW final find 8 = cal label find after scan 9 = cal label find prior to standby 10 = doc original find prior to standby 11 = bulb warm up from standby
I would see if there is an original on the flatbed glass (platen), or if something is obstructing the scanner view.
If the error persists, replace the scanner assembly or the formatter pcb
Hi The option you have is to check and make sure the connection between the formatter and scanner formatter are properly seated. The 79 error you are getting means you should try and do a firmware upgrade it could be giving you a problem and more than likely fix the issue.
