How to Identify and Fix Common Problems ?

Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded. Make sure you loaded the printable side of the paper correctly for your product.
If your printouts are blurry or smeared, try these solutions: Make sure your paper is not damp, curled, old, or loaded incorrectly in your product. Slide the edge guides to the edges of the paper. Use a support sheet with special paper, or load special paper one sheet at a time.
If your Epson printer is printing out faint images, skipping lines, or is streaking your image with lines, chances are you have a clogged nozzle–a common problem many users have with Epson printers. It`s unavoidable that print heads clog over time as small amounts of ink residue dry up and collect in the nozzles.
Line printers make use of continuous form paper which is usually perforated instead of individual cut sheets. Line printers print the full width of the page, one line of text at a time, instead of a print head moving back and forth across the page.
A blueline is a print of an ad, brochure, or other advertising materials produced on photosensitive paper (hence the blue color). This process was once used to confirm the location of all artwork, headlines, graphics, and text components before printing.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
A common cause of faded, faint printouts from your inkjet printer is dried ink particles causing a blockage in your printer. The printheads on an ink cartridge can be become blocked if the printer is not used for a period of time, so it is recommended to print a few pages each month to maintain the print quality.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
There are four primary causes for horizontal banding on prints from inkjet printers, (1) nozzle clogs, (2) mis-aligned print heads, (3) low quality print settings (4) incorrect paper thickness settings. Below we will describe each of these causes for horizontal banding as well as ways to try and fix them.
The types of line printers are drum printers, band-printers, and chain printers. Other non-impact technologies have also been used, as thermal line printers were popular in the 1970s and 1980s, and some inkjet and laser printers produce output a line or a page at a time.
: a line printer in which the printing element is type carried on a continuous chain.
Whiteprint describes a document reproduction produced by using the diazo chemical process. It is also known as the blue-line process since the result is blue lines on a white background. It is a contact printing process which accurately reproduces the original in size, but cannot reproduce continuous tones or colors.
The blueprint process
When the paper is illuminated, a photoreaction turns the trivalent ferric iron into divalent ferrous iron. The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide (Prussian blue or Turnbull`s blue) with the divalent iron.

Thus, for an easier-to-read image, drawings started having a solid white background, and blue lines delineated the image. The process, however, changed very little: Instead, only the lines drawn on the original appeared on the copy.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
If your printer is printing in blue it is out of yellow ink. and if only cyan or light blue is printing red is also over. Get your cartridge replaced or refilled the printer will start printing properly.
Printers may produce poor quality printing if they are exposed to too much heat. Don`t place your printers in a high-temperature area or near other devices that produce excess heat. In addition, keep them away from windows, where heat and humidity can be high.
