Epson Rx420 Hi When printing from the computer only half of the image/a4 text gets printed on the right hand side the left hand side is totally blank....... i have cleaned heads and performed all the necessary configs within the program - i have even reloaded the software. printer is epson rx 420 computer is Hp dimension 5000 - OS winXP problem has started this week any ideas?

What application are you using to print text? Word?
Try a simple application, like Notepad or Wordpad, to print some simple two-liner text.
Does printer print ALL the text on left side or just the half of printable material?
Even if you are indicating that page size is correct, looks to me some problem with the selection of print area.

COULD BE THAT THE PAPER IS BIGGER SIZE THEREFORE CUTTING.NEED TO SAY FIT TO PAGE ON YOUR PRINTER DRIVER

You can do several tests to understand where the problem is.1. Try to print a test page - Go to Printer Devices - Right click your printer and select Properties - Click Print Test Page button like on the picture below
If the result is still like your description, you are facing hardware problem like defective toner cassette or drum.2. Try printing from different sources - print a page from your browser like Internet Explorer - print a page from your Office Application like MS Office or OpenOffice - print from notepad - print from Image viewer application
If your printer prints only the left half of the page - this is definitely hardware problem. If you receive different results from different sources, find out wich one of them does the described printout and try to discover the setting that causes the problem and restore it.Sometimes when we talk about MS Office this problem is caused by Print Area setting. You can just Clear this Print Area from Page Layout like on the picture below.
I hope this was useful information for you!

have you set the page setup in document is same with page setup at print setup. Some new epson printer use paper sensor to measure the paper width. If page setup wider than actually paper inserted, the printer will print only half page. example : Your document 10 cm wide, page setup 20 cm, and you insert 10 cm paper wide. It will print only half of 10 cm, 5 cm.

My suggestion would be to totally un-install the printer and erase all traces of the driver(s). Search for them after the un-intall and erase them manually.

Re-install the printer and driver...reboot if nessasary...align the print heads...do a test pattern...then try and print your document. It might just be a corrupted driver...some would suggest just installing over the existing driver...but I've found doing it that way gives you the best chance of it working the first time.

Move envelope/A4 lever near paper output tray until the letter L registers on display. Print in this mode and you should have full page printed.

I've had a look at the user manual (which was very vague) but found that under the "Product Information" > "Control Panel Functions" there's an option to have A4 or 10x15cm sized paper output on the printer control panel. Make sure that the A4 selection is lit before you copy.

Hopefully that will help resolve the issue.

the paper was not going in straight, I packed the tray with lots of paper and adjusted the paper lever tighter. Goes nicely now.

Another post suggests that you printer is dead -see (http://www.fixya.com/support/t354202-epsom_rx_425_just_prints_half_page) but I've had the same problem - things seem to be ok after I reset to the defaults in the main page of the printing preferences.
