I've gone through the basic troubleshooting for my printer, I have an HP 1400 PSC and it normally works great, but now whenever I print anything, the text is blurry. I haven't been able to figure out how to do the cleaning that you can do, I don't have my manual and there's nothing I can find to tell me how to do it. I changed my print quality to best, and all that did is make it print much slower, it is still blurry. The paper type is correct. Can someone tell me how to fix this please? Thanks!!
