Problems & Solutions
(Printer Friendly Version provided by Thummaji's
In this you will find
most of the printer problems based on Dot Matrix Series (LQ1050+ series)
because i worked with them.
1Q: When taking word table printouts It is not
printing Vertical Lines at some point, this is done in LQ 1050+DX in
Ans: For this i found that the problem occured at the
printer properties. These printing properties selected as graphics session
resolution to 120X180 actually that will be default 180X180. I want to
clear one thing here that when 120X180 is there it is coming sometimes but
that is not coming for having more table columns. The problem may come
even when the Printer head pins gone inside little bit. By increasing the
graphics you can get the correct result.
2Q: My Customer Suddenly called and said my
printer is printing some funny characters (jumble) when given print?
Ans: I know the solution for this problem and simply without seeing his
printouts I went and fixed the cables at printer, system side correctly
and said give the printout, then he got the correct. so, checkout when you
call your hardware engineer.
Here i want to tell, two points, one is when you
selected already installed different printer driver then the problem will
come but here you can observe small amount of characters will print.
Actually what happens the driver converts all the info according to its
printer. And second one is when the cable is not connected correctly the
data will receive by printer is wrong that is contacting of pins is wrong
and you will not get correct printout. so watch out, dont blame others.
3Q: When my customer called and said suddenly
the printing has stopped and Iam facing this problem since three, four
Ans: So i went there and i observed that the customer is not taking care
of his printer . because it is covered with lot of dust and papers. I
observe that printer roller is stuck with all these. Then i cleaned every
thing, and cleaned roller, serviced with machine oil (which is light
machine oil). The problem is solved and now he is getting correctly. What
happens some people don't care of their things and they will get these
problems when they are in deep trouble or hurry so keep clean and you will
get more life of your system and printer.
4Q: Problem is the printout is taking more time
compared to earlier days?
Ans: Again here you can observe two things when the printout time is long
one is for the above is it requires cleaning (service) and oil on the
roller rod, settings changed to other than draft, more than 10 CPI. so
checkout the above and you can get the correct results. Second one is in
the printer properties details section spool settings are set wrongly that
is you have selected directly to the printer option. so change that to
start printing after first page is spooled. the above setting directly to
the printer is use full when the printer is having more memory (Printer
contains memory i.e., more for laserjets). By using this you can take the
printouts when the system is off also. because they are in the printers
5Q: Printer is not printing all the lines, i.e.,
it is printing 3/4 of the paper?
Ans: Here you have to observe the printer page settings, application page
settings which may conflict some times. what happens in some printers is
the printer can't find or detect the paper length automatically but it
takes from the system which are set by the user and prints that much
content, the rest in another paper.
I Faced this problem with Apollo color printer when
it's properties spool data format set to some user defined. So i removed
that one and given printout then that is working find.
6Q: When the printer is printing, suddenly the
ribbon is coming out of the head set?
Ans: This Problem will come when you're ribbon set is not correctly
adjusted or the main reason is that you didn't have ribbon mask which will
hold the ribbon between the roller, head coming upside. This ribbon mask
causes to hold the ribbon coming upside. The ribbon mask is having some
edge so that it can hold the ribbon coming up. This is placed at the
middle position of roller and head watch for the thin steel plate.
7Q: In the LQ1050+Dx printer the paper is not
feeding automatically when i insert the paper, at least any solution
without moving the roller manually?
Ans: For this the main reason is at the location of paper insertion you
will find the button which will make the printer to take paper inside.
When we insert the paper that the button will be pressed by the paper so
that, this will be activated. If this is not coming you can feed the paper
by pressing Load/Eject button (make sure Offline). So clean the button of
auto-feed then you can get the result.
8Q: When my customer said, Suddenly my printer
become slow, and printing is coming light?
Ans: There i observe that he has adjusted accidentally the lever to
mulipart paper and taking single paper print. This will make some how slow
compared to earlier. For light printing my explanation to him is actually
the head pins are down and they are not that much enough to strike the
9Q: In the HP Deskjet 840c printer I am unable
to feed the paper correctly?
Ans: For this there are many reasons. one of them is paper feeder problem.
Actually i faced the problem is my client has not arranged the paper
feeder inside. instead he adjusted to the backside. And another thing is
sometimes the roller which is placed at paper feeding may have lot of dust
Some tips to take printing correctly.
1. Keep the Printer roller, Head Rod clean so that those two can move
2. Don't keep books, material on them. I observe in offices all the pins,
waste papers inside.
3. Adjust the multipart paper feeding correctly.
When you are taking two copies using carbon adjust that to 3, because, we
have to consider carbon paper also one.
4. When ever you are inserting the paper see whether that is offline or
5. When you inserted the paper correctly dont forget to press online
button to get offline to online.
6. If that is printing funny characters checkout the connections.
7. Dont move the head manually when the printer is ON.
