| Query It is very frustrating why my HP 4520 printer not printing black ink correctly. It is printing very blurry or grey. I have examined the ink level of the black color cartridges, and it is three-fourths filled. Sometimes it prints the blank pages. I do not know why my printer not printing well. Even I have updated windows and all the printer drivers and software. I must say, we are using genuine HP cartridges. Please help me with some troubleshooting guide to fix this printing issue. |
