SOURCE: Flashing Lights on HP 690C - Won't Print

Hi Stev, First I know this is going to sound strange but have you disconnected the printer cable from the printer itself? (not the computer) If not try unplugging both the parallel and power cables for 30 seconds, then when you reconnect and power up hit the resume button. I've seen problems in the past where a job was killed like that and the printer would not work until the parallel cable was removed from the printer. The light pattern you describe, resume light blinking with the power light on, can mean any one of the following things on that model HP. 1. Top cover is open. Open the top and make sure there is nothing keeping the cover from closing all the way. Don't forget to check the underside of the cover for something stuck to it. Close the top cover. 2. A print cartridge is missing or an incorrect print cartridge is installed. Install the correct print cartridge. AND/OR Verify that the print cartridge is properly snapped into place. Close the top cover. 3. Printer detects an out-of-media condition. Load media in the lower (IN) tray and press the Resume button. 4. Media is improperly loaded. Remove media from the IN tray, re-square the stack, and reload. Make sure that the media-width adjuster and media-length adjuster are against the stack of media. Make sure that media is not buckled in the IN tray. Verify that the media-width adjuster is along the left edge of the tray and is pushing the right edge of the media against the right wall. 5. The printer timed out waiting for a form-feed command. Press the Resume button. The page will eject from the upper (OUT) tray. 6. Printer detects out-of-ink condition. Replace the print cartridge and press the Resume button. 7. Dirty Cartridge Contacts Use a clean foam-rubber swab or lint-free cloth slightly dampened with water. (Distilled water is recommended. Tap water might contain contaminates that could damage the cartridge.) Locate the copper-colored circuitry strip on the back of the cartridge. Clean the copper-colored strip with the dampened swab or cloth. Do not wipe the nozzle end of the cartridge or touch the silver-colored nozzle plate on the bottom of the cartridge. Unplug the power cord from the printer. Clean the carriage contacts on the back wall of the ink cartridge carriage with a damp foam-rubber swab or lint-free cloth. Use a dry foam-rubber swab or lint-free cloth to remove the moisture from the contacts. If the carriage contacts show noticeable damage, contact the HP Customer Support Center listed in the printer's User's Guide. Plug the printer back in and try printing again. 8. Printer detects paper in the paper path. Turn the printer off and open the top cover. Make sure that paper is not jammed in the printer. Lift the right black rectangular paper sensor (located in the middle of the printer just below the silver rod on which the cartridge carriage slides) and make sure that nothing is stuck under the paper sensor, perhaps by blowing under the sensor. Close the top cover and turn the printer on. Try printing again. If none of this helps let me know and I'll see what else I can dig up on the problem. El Duderino

SOURCE: Problem with HP 7450 and "Paper Jam"

hi, mezz

try this

There are 2 different types of flashing patterns with those two lights on the printer.
***
Resume light and power light BLINKING ALTERNATELY
Problem: Paper is jammed in the printer.
***
Resume blinking SIMULTANEOUSLY with power light

Problem:
The print cartridge carriage is stuck.

Solution:
1. Open the top of the printer.
2. Remove anything that is blocking the carriage path.
3. Turn the printer off.
4. Turn the printer on.

Problem:
There is something wrong with the printer. (I didn't write it, I am pulling this from actual HP tech documents, so don't blame me on this one) :)
Solution:
Turn the printer off.
Turn the printer on.
If the printer will not turn off, unplug the power cable from the electrical outlet or wall outlet.
Unplug the power cord from the back of the printer.
Wait about 30 seconds.
Plug the power cord back into the wall outlet.
Plug the power cord to the back of the printer.


oke, post in me back

SOURCE: Can't print because of Error-offline status.

I found out that the IP address on the printer was different from the IP address that was available when the printer was first installed. After spending days trying to fix this, it was resolved in less than two minutes.
Go to the Printer Folder in the control panal and choose to Add a Printer. You will see the option to add the new printer ( wireless). Chose to install, and it will install the printer under the new IP address. It worked instantaneoulsy.

You also need to make sure the IP address is inputted into the printer ( check your guide for how to input the IP address)

What I dont know how to do is to keep the IP address static. Afger, it is not practical to do this each time it changes. If only the last digit changes, it may be as easy as switching to the printer available under the current IP address.

Cheers,

See this notice about the flashing light. Then see this article, particularly step 4. You may need to clear the print queue & restart the print spooler. Make sure you reboot your system. If that doesn't correct the issue, try a power reset as described here before uninstalling or reinstalling the printer software.
The printer uses your system memory to print from, and communication glitches do occur.
Good luck.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

SOURCE: blinking/flashing lights(orange & green) &

that is because ur head of ur printing cartridge is damaged.

remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head install both cartridges on ur printer n check ur blinking light on ur printer that will work only if u r too lucky other wise u have to purchase a one cartridge.
