00:00:05
good afternoon everyone, a master class from
00:00:09
us, my name is Andrey Tarasov,
00:00:11
I am the leading technical specialist of
00:00:12
the company, our agency series, we
00:00:15
continue to look into poverty, these
00:00:17
faults were copied a lot of
00:00:19
snowstorms, today we will look at the characteristic
00:00:21
problems that arise at the stage of
00:00:23
transferring an image from a photo, fighting us
00:00:26
from paper,
00:00:27
as always, let's start with the most
00:00:29
common variants of the
00:00:31
transfer roller, also called the roller, 91 types of
00:00:35
image defects light spots along
00:00:38
one line or a light stripe
00:00:40
of overprint along the direction of paper movement the
00:00:43
distance between the pleasant world is equal to the
00:00:45
circumference of the
00:00:47
transfer roller possible causes of a
00:00:49
defect contamination or damage to the
00:00:52
transfer roller
00:00:53
contamination damage to the soft
00:00:55
surface of the transfer roller increases it
00:00:57
electrical resistance
00:00:59
that makes it difficult to transfer the donor from the
00:01:01
surface of the photodrum to the paper
00:01:03
ways to eliminate dirt from the surface of the
00:01:06
transfer roller can be carefully removed
00:01:09
using a dry lint-free cloth if
00:01:13
the defect is not eliminated or the roller is damaged
00:01:15
replace the transfer roller
00:01:18
important note porting the
00:01:21
transfer roller with a damp cloth is unacceptable this
00:01:24
can cause problems in the process dry
00:01:26
electrostatic transfer the second type of
00:01:29
image defects a
00:01:30
print with a very faded image a
00:01:32
disk of almost white possible causes of
00:01:35
defects there is no contact of the
00:01:37
transfer roller or a faulty
00:01:39
high-voltage payment
00:01:41
the image is slightly transferred from the
00:01:43
photodrum to the paper only due to the
00:01:45
physical pressing of the paper to the drum
00:01:47
solutions clean the
00:01:50
electrical contacts of the transfer roller
00:01:52
lubricate with electrically conductive lubricant if
00:01:55
the defect has not been eliminated, replace the
00:01:57
transfer roller or high-voltage board; third
00:02:01
type of image defects;
00:02:03
the image has a gradient with lightening
00:02:05
towards one of the edges of the sheet;
00:02:07
possible causes; defects;
00:02:11
one of the sliding bearings of the transfer
00:02:13
rollers is worn out or broken; which causes the roller to skew;
00:02:17
ways to eliminate it; check and, if
00:02:20
necessary, replace the
00:02:21
sliding bearings of the roller; transfer,
00:02:24
also called bushings, an
00:02:26
important note in a number of models such as
00:02:29
xerox work center 3220 wear of only
00:02:32
conductive bushings can lead to
00:02:34
long procedures for the device to be
00:02:36
ready after turning on the power and
00:02:39
also after sending a print job
00:02:42
fourth type of image defects dirt
00:02:45
on the back of the print
00:02:47
possible cause defects contamination
00:02:49
toner transfer roller, this can
00:02:52
occur due to donor spillage from the
00:02:54
developing unit, as well as if the
00:02:56
paper size is smaller than the image size
00:02:59
in the drum, ways to eliminate the
00:03:02
first case of toner spillage, find out
00:03:05
the cause and eliminate if necessary,
00:03:07
replace the cartridge or developing unit,
00:03:11
secondly, in many models,
00:03:14
contamination of the transfer roller are eliminated
00:03:16
automatically during breaks between
00:03:18
making prints if
00:03:20
self-cleaning is not enough, then dirt from the
00:03:23
transfer roller assembly can be removed
00:03:25
using a vacuum cleaner or a dry lint-free
00:03:27
cloth if the defect is not eliminated or the
00:03:30
roller is damaged replace the transfer roller
00:03:32
third if the defect is caused by the
00:03:36
paper size being smaller than the image size on the
00:03:38
drum set the appropriate
00:03:40
format paper,
00:03:41
now let's look at some of the problems that
00:03:43
arise when using a
00:03:45
transfer ribbon at this stage of the printing process, the
00:03:48
first form of image effects is dark
00:03:51
stripes on the back of the print.
00:03:54
Perhaps the cause of the defect may be
00:03:56
that the built-in cleaning mechanism of the
00:03:58
transfer ribbon is worn out or full of
00:04:00
waste toner and paper dust;
00:04:03
in addition, wear is possible the transfer tape itself
00:04:06
since it has a limited resource
00:04:08
of use ways to eliminate
00:04:11
it clean the cleaning mechanism of the
00:04:13
transfer tape if the defect is not eliminated
00:04:15
replace the transfer tape and the cleaning mechanism the
00:04:19
second type of image defects a
00:04:21
print with a very faded image
00:04:24
the sheet is almost white possible causes of
00:04:26
the defect there is no electrical contact in the
00:04:29
assembly tape 99 is faulty high-voltage
00:04:32
board, the image is slightly transferred from the
00:04:34
photodrum to the paper only due to the
00:04:36
physical pressing of the paper; the photodrum
00:04:39
solution is to disassemble and clean the
00:04:42
transfer ribbon assembly; wash the shaft and
00:04:44
transport and charge the tape; check the
00:04:48
connection of the electrical connectors with a
00:04:50
hub; then transfer, if necessary,
00:04:52
replace the assembly; transfer methods or
00:04:54
high-voltage board; conclusion; let’s
00:04:58
consider it sufficiently now a rare
00:04:59
transfer corotron device, the
00:05:01
first type of image defects are light
00:05:04
stripes along the direction of paper feeding;
00:05:07
perhaps the cause of the defect was on the nick of the
00:05:10
corotron or oxidation of the mickey and methods for
00:05:14
eliminating the loss of the corotron filament with a cloth
00:05:17
moistened with isopropyl alcohol
00:05:19
using tweezers in case of oxidation of the
00:05:22
surface of the nick, ordinary cleaning may not
00:05:25
help, you
00:05:26
can use a piece of fiberglass and
00:05:28
years of textolite with a notch that
00:05:31
allows you to carefully remove the oxide until the
00:05:33
filament shines; the
00:05:34
resulting dust must also be removed
00:05:37
if the defect is not eliminated; it is necessary
00:05:40
to replace the filament or the transfer corotron
00:05:42
assembly; the second type of image defects is a
00:05:44
white sheet; a possible cause of the defect is the
00:05:48
absence of a high-voltage
00:05:49
transfer voltage, which can be caused by a
00:05:52
short short circuit to the body due to a break in the
00:05:55
transfer corotron filament or a
00:05:57
malfunction of the high-voltage board;
00:05:59
methods of elimination; ensure the
00:06:02
integrity of the transfer filament; check the
00:06:04
serviceability and clean the contacts of the
00:06:06
transfer corotron; no breakdown on the
00:06:08
device body;
00:06:09
if the defect has not been eliminated; replace the
00:06:12
transfer corotron; and, if necessary,
00:06:14
replace the high-voltage power plan;
00:06:16
so we have analyzed the most typical
00:06:19
problems arising at the stage of transferring an
00:06:21
image from a photodrum to paper,
00:06:24
