Hi, Alois, 1. Yes, plates are gummed. Gumming section is checked every morning. 2. Time between making plates and press is between 1 and 5 days. 3. After all I will try to read all about F/S chemistry, because I start to understand that when problem occur in the press, first what pressman think...

We are working with over 20 small to medium printing plants. Most of the time all customers are happy with our plates. Only few days in 3-6 months some customer start to report about this problem. We are using Agfa gum and not changing type of plates (mostly very good but chinese or taiwan...

Hi we are ctp bureau. Time to time some our clients send us prints on attached photos. It's happen immediately after printing start. After cleaning with plate cleaner, problem solved. We are producing plates for many printers. Some clients are happy when somebody reports such problem. Everything...

Finally the problem solved. The Machine working seamlessly. It's hard to explain here all details because of a lot digging and reading. With few words. Motor has changed without big success. Final result was reached after changing some parameters of servo. All errors disappeared. If somebody...

Hi guys, Some new results (machine still not working). 1. Servo work well in speed mode (slow and fast rotation). 2. Every operation in positioning mode finished with "Servo does not enter the Ready status. 3. Servo after every positioning operation send hardware signal Ready. It's mean that...

Of course the device is leveled.

Mr Ramirez, please explain again a bit more about "Tune" on Pio and A0. Without initialization from service menu Drum rotating Slow with no error but too big vibrations in the belt. Belt tension is ok. I can order motor, but maybe the problem is in the servo pack? Looks like servo pack have not...

Hi Aleksey I already ordered a new belt. The old belt vibrates all the time, but not too much. Interestingly all of this happened after the Adjust Offset procedure. Current status after error is 850A - 0099. Here is the picture too.

Thank you, Greg I look at the same direction. When I try to execute Go to Leading Clamp position, motor are going to some position, but reaching wrong one.

Hi guys How to solve the problem: E0127 - Servo unit does not enter the "Ready" status. 2 years few times per day Ptr4300 gave error: E0127 - Servo unit does not enter the "Ready" status. Finally after executing: Adjust offset from Input parameter/Drum parameter screen, this error reached...

Please read your private messages :)

Sorry about my english I'll try explain again. The image on the exposed plate is slightly rotated against the plate, which means that the plate is loaded slightly diagonal on the drum. Frequency of the problem is 1 from 5 loaded plates. With 0.3 plates there is no such problem.

Hi guys problem with Lotem 400v - 2001, manual loading. After all there is often small diagonal errors (something like 0.5mm - 1 mm) when working with 0.15 plates. Any idea where to look? In loading system? In gripper rollers? Anywhere else? With 0.3 plates there was no errors at all.

You turned out to be 100% right. Thank you!

Hi guys we have Lotem 400v with 24 diodes. Machine is working very well with .3 plates from different suppliers. The problem is that using internal tables for laser power plates .15 are too underexposed. We try to increase laser power by 10-15% but with no good result. Any opinion will be helpfull.

In my opinion your problem is different. Input and output rollers bars bend the plate around drum. You need to see what happen in loading module. It's easy to disassemble it and see quality of rollers, pressure, etc.

All resistors in digital inputs are grouped in chips. You need to start debugging when you know what is not working. Following the wrong signal and measuring with avo-meter and oscilloscope you can describe part of the plate. Reading parts signatures you can exactly restore schematic and...

The board is too pricey. After few days of hardware debugging I repaired my board adding only one resistor.

Just with bending them.

To Armya Inc - very good reading. To ansoft I ask about P102 and P74 comparison? Actually P102 can be PT-R8000II or PT-R8300. P74 is 4300. Both are 32 ld devices. Loading of the same plate on 4300 is not faster than on 8xxx series, or here is very small differences. The question is what is the...
