How Inkjets Work In Theory
Part 1All right, so you have an inkjet printer.
The major parts: Please do yourself a favor and have your printer in front of you. This way you can locate and identify all the parts listed and gain an understanding.
This may seem dull but serves the purpose of overall success.
Main board; (also known as motherboard).
This is generally located where your printer cable plugs in and in most cases plugs directly into the motherboard. This part takes the information from the computer and
re-assembles the information and directs the printer components to start to work to form your printed page.
Printer Carriage; (Also know as the cartridge holder).
This part holds the cartridges and is located and rides on a round shaft.
The Print Carriage receives data from the motherboard and makes contact with the ink cartridges and tells them when to fire drops of ink onto the page.
Carriage Shaft
This part allows the printer carriage to move smoothly back and forth while ink is being dropped on to the page.
Carriage Belt
The Carriage Belt can be located near the carriage shaft and is parallel to it.
It looks like a long belt. It actually pulls the printer carriage back and forth
along the carriage shaft.
Carriage Motor
This motor is commanded by a Main Board to turn on and off in order to position the carriage in the precise location for Ink to be dropped onto the page.
Encoder Strip; (Not all printers are equipped with this part).
This strip is located behind the Printer Carriage and actually runs behind and thru the Printer Carriage. It is made of somewhat clear plastic with little lines on it. There is also an electronic eye behind the Printer Carriage that reads the lines and counts them so as to determine the proper location of the Printer Carriage. Pretty neat!
Paper pick-up rollers
These rollers are located in your paper tray.
This name kind of tells on its self. These rollers are responsible for executing the command to pick-up paper at the correct time. The Main Board gives such a command.
Feed rollers
These rollers take up the duty of feeding the paper through the machine and are generally located second to the paper pick-up rollers in line.
Delivery or Exit rollers
You can find these rollers at the point where the paper exits the machine.
(Some machines use the feed rollers for this also).
Paper path
This is any area in which the paper travels through the machine.
Service Station
This very important part is located where the Printer Carriage carries the cartridges and takes them to their place of rest when not in use. This part keeps the inkjet cartridges clean and sealed when not in use it is like the Butler. It is generally on the right of the machine.
Interesting Facts
· A basic inkjet cartridge has 50 nozzles about ½ the diameter of a human hair.
· A tiny electrical part heats up the ink and the ink bubbles and this happens 3600 times a second for each nozzle.
· The bubble grows for a precise time and size and is then ejected out of a nozzle and on to the page.
· An average cartridge in its lifetime of use will eject over 120,000 million drops of ink.
· It can take up to 25 drops just to make a number l show up on a page.
· When in full swing the 50 nozzles fire up to 180,000 times per a second!
INCREDIBLE STUFF!
How Inkjet Printer Work In theoryPart 2You turn on the printer. It starts to make sounds and lights flash and there is noticeable movement. All the troops are checking themselves out and are reporting to duty.
The computer sends a document over to the printer in computer code. The printers’ Motherboard takes the info and puts into action. It tells the carriage and cartridges to get ready. It sends signals to the paper feed rollers too. It tells the paper feed rollers to pick-up the paper and when it enters the path near the carriage the carriage motor takes the carriage over to the first line. The carriage tells the motherboard it has arrived and is ready.
The paper runs over a sensor that yells hey the paper is here and the Motherboard; says to the carriage fire those cartridges in this order and color and do it now, pronto.
Well I hope you get the idea.
