In the last issue, we talked about how to use copy paper, and in this issue, we will talk about the common problems of copy paper.
1.What are the characteristics of high-quality copy paper?
Appropriate thickness, good copying effect;Proper smoothness for clearer images of the copy;The size and specifications are consistent, the paper cut is flat, and the edges and paper dust are attachedParticularly less static electricity, prevent paper jams and paper jams;The moisture content of the paper is low, the copy is straight, and the photocopying is smooth;No paper powder, keep the copier operating normally;High opacity, especially suitable for double-sided copying.
2.What are the hazards of poor copy paper?
Paper jam, paper jam in the conveyor system;Wear the drum, dust adsorption on the drum surface, friction increases, resulting in serious wear and tear and reduce the life;The copy is blackened and the handwriting is illegible;The paper output part is jammed, the inside of the copier becomes dirty, and the dust increases.
3.Why is the paper inlet of the copier often blackened?
This is because printing paper with static electricity is used, and printing paper is not afraid of static electricity. At present, there is a lot of phenomenon of printing paper mixed with copy paper, which is very damaging to the copier, so you should pay more attention when purchasing.
4.How is the white dust that is often found in photocopiers produced?
I used ** copy paper with a lot of dust on the surface. These crumbs are one of the important causes of damage to photocopiers.
5.Why is the freshly copied paper so hot?
This is because in the final stage of the copying process, the paper passes through a set of thermodrums and rubber rollers. The function of the thermodrum is to melt the toner that makes up the image and press it against the paper to hold the image. The heat of the drum can reach up to 200 degrees Celsius, so the copy is hot as soon as it is copied.
6.Why do paper jams and wrinkles sometimes occur when copying?
It is possible that the moisture content in the copy paper is too high, and when the water passes through the thermodrum, the water turns into steam due to the heat, causing the paper to expand and be pressed into wrinkles by the rubber rollers that operate with the thermometer. Another possibility is that the uneven pressure of the rubber roller due to too long has caused wrinkles in the paper, and in addition, it is possible that the paper is too soft due to poor quality and insufficient density, especially when copying on both sides.
7.How should electrostatic copy paper be kept and stored?
Attention should be paid to the following points: the copy paper should be stored horizontally and classified according to different specifications, the shelves should be neat, and the format label should be eye-catching, so that it can be easily accessed at any time. It is best stored in a ventilated, dry place, or stored in a professional drying cabinet.
8.Is the thicker the copy paper, the better?
The thinner the paper of the same weight, the higher the processing level, the greater the density, and the better the moisture resistance, stiffness, and copying effect. On the contrary, the copy paper cut by the printing paper is thicker, softer, rougher, and has a higher moisture content, and the greater the damage to the copier.
9.What happened when the copied document turned yellow and brittle after a while?
This is due to the addition of too much cheap filler to the copy paper used.
10.What are the reasons for poor photocopying?
1) The smoother the paper, the clearer the photocopying, and the better the photocopying effect
2) Uneven moisture and thickness of the paper will lead to uneven photocopying
3) Moisture on the surface of the paper ash will lead to spots.
In the next issue, we will talk about how to choose a good copy paper.
