Weld not found

Sounds like a failing weld sensor. Clean it first its on the left side, you can see it when the ribbon is out. If that doesn't help replace it.

All of the newer printers have ink tanks that are 'chipped out', meaining that you can't just refill a tank with a syringe like in the olden days. If the printer reads the 'chip' on that tank and it says it's empty - it won't work even though there is ink in it.
Some refill places just put ink back into used tanks, but DO NOT have a chip re-setter, so the printer does not either: 1) recognize the tank, or 2) thinks it is still empty.
I have had very, very good luck with an on-line company called ABCINK.com for my Canon MX700. A five pack ( 2 Black carts. and one each of cyan, magenta and yellow) costs me only $18.95 delivered w/shipping. Genuine CANON carts. would have been almost $100.
Your Canon 300 is older than dirt. I know, I had one. Try another ink tank or attempt to CLEAN the print heads and nozzles. But really, I bought one of these old dinosaurs for $30 bucks 10 years ago, so you may want toss this 'boat anchor', because as soon as you, and if you, can get it back up and running - something else will fail.
Go drop $60 on a brand new 4-in-one printer that scans in documents & pictures, can scan in a printed page and convert it to a Word doc using OCR (Optical Character Recognition), makes copies, prints from your computer and has an Automatic Document Feeder and Reader so that you can load up 50 pages to copy, scan or whatever. (Also, it might be time to replace that old Penty 3 processor. FWM, Freekin' Wal-Mart has some ****-Jimdy 15.6 laptops for $325 - $350 out the door with tax and a whole ONE year warranty.)
DO NOT BUY A H-*** MACHINE. THEY ARE JUNK. THEY ALL OVERHEAT & JUST RECENTLY THEY QUIT MAKING THEM. REMEMBER THAT COMCRAP (COMPAQ) GOT BOUGHT BY H-***, SO NO **** FROM COMCRAP EITHER.)

Run a few "print-head-cleaning" cycles, to get the black ink flowing through the ink-jets inside the print-head.

Some printers REQUIRE an "alignment" step every time you change the ink-cartridges.
It only takes a few minutes, and it prints one or two pages of paper.

It sounds like you need to "prime" the printer. Look for the Utility that came with the printer. It may even be where you found the "test print" page. If that fails, check the documentation that came with your printer, and see if the print cartridges also contain the printer head... like the HP Inkjet printers do. If not, I'd say there might be something wrong with your print head and it needs replacing.

If you no longer have the manual that came with you printer, log onto the Lexmarkwebsite, support, and find your printer manual. If all else fails, call Lexmark's support line.

I hope that helps. Good luck!

Hi there maximum time we found it is a the head problem. The print head is what the cartridges sit in inside of the printer. For resolve the problem please follow these.
Open the printer and wait for the carriage to slide over. Some how if its not come then Unplug the printer & Manually slide the carriage. Now Remove the ink cartridges from the print head & Use wet warm cotton swab or use alcohol to thoroughly clean the print head. Repeat this until there is no ink residue coming off on the cotton swab. After finished it make the head dry then fix it back. Now Try to print something now If that does not work then follow the next step.
Remove the printer data cable & restart the PC & printer. Then fit back the data cable & turn on the printer. Hope that's start working , if no luck then Uninstall the printer driver & restart the PC & Printer both again. Now install the driver of the printer and connect it with PC ,Turn on printer & go for a test print from the printer preference. Thanks & waiting for your reply.

One place to find the print spooler (queue) is from the start button. Look for Printers and Devices (IIRC) in the list on the right side near the Control Panel link. Click on the command and then double click on your printer, then click on See what's printing or the line about the printer queue. (or right click on the printer and choose see what's printing). From this control panel, you will also see a triangle if there is an Windows device error and can troubleshoot that error.

Sometimes the problem is something stuck in the queue that can't be deleted. In that case try stopping and restarting the spooler. Start > All Programs > Accessories > right click on Command Prompt and select Run as Administrator. In the subsequent window, type "net stop spooler" without the quotes followed by hitting enter. On the next line, type "net start spooler" again without the quotes and hit enter. After that command executes, restart the computer. Check the spooler and try printing again. (If you get a query about stopping other services, type Y and enter. The service will restart on rebooting.)

I hope this helps.

Go to Printers & Faxes, open your printer (the window where you see the documents being printed), and from the upper menu leftmost item (Printer) uncheck the option "Work offline" or similar. Then try resuming or restarting print.
