It's
been a few months
since I've been at NATC and would like to share some of the jobs I've been
involved in:
Fake
toner cartridges
On
a rainy day, we went to site diagnose a faulty HP CP 2025, a laser printer,
which was not printing clearly i.e. it had smudge marks. Nickson and
I arrived on site and to find that
the printer was very dusty and needed to be serviced. We separately
serviced each
part i.e. the
scanning unit, fuser unite, and
image transfer belt. This
immediately resulted in better print outs. However,
there
was still a yellow smudge. Further
checks
revealed that
there
were fake toner cartridges in the
printer. Fake toner cartidges often start leaking ink and can damage
the
image transfer belt. We were on site for 2 hours.
Relocating
an intercom
We received a call from one of our new clients: one of the intercom telephone extension was not working as the cable connection was faulty and may have broken somewhere. The only way to resolve this problem was to replace the cable completely from the PABX unit to the wall outlet of the user.
We decided that instead of running a long cable all the way from the user’s desk to the PABX room which would have to be done externally it would be more neat to extend a cable from the conference room located very close to the user.
Then our first target was to test and get the conference room line activated. We checked one by one the connection with the PABX and at last we have a tone in our conference room telephone.
Then we ran a Cat6 cable to connect from the conference room line to Desk 6 where we needed to activate the connection. We installed the cable neatly and made a new wall connection for the user on Desk No. 6. The phone is working now.
The user was allocated the exact same original extension number.
Daniel
gets a new laptop!
We
recently received a 'condemned' laptop from our US office. Since
diagnosis fees can be higher
in the US, our colleague told us the laptop was ours in case we could
diagnose and repair it! The plan was to repair the laptop for our
trainee, Daniel. I turned on the laptop but the internal and external
screens didn't come on. I checked the parts and found a
faulty IC in the
VGA section. Luckily, I
could harvest
this part from one of our motherboards. I replaced the faulty IC and
the laptop came on! It was as good as new and, now Daniel has his own
work station!
Downgrading
the
OS
We
were to supply a new Lenovo H505S desktop to one of our clients that
came pre-loaded with Windows 8. however the client requested Windows
7. I was stuck - how would I boot from the CD-ROM? After some trouble
shooting, I found that the exact location in bios from where to
change the boot options. We ran Windows 7 Ultimate but we needed to
also install the system's drivers. We had to download them. The VGA
driver was 172 MB and the audio one was 140 MB. We downloaded and
installed all of them. We also installed Office 2010.
After
all the work we did and delivered the desktop, the next morning, the
client told us that they need at least a 2 Ghz processor to run their
accounting software.
OMG!
We
repeated the whole process with a new desktop with a 2.5 Ghz
processor!
It's
the fuser!
We
received a call about a faulty Canon LR 2018 Printer which was not
printing. The error code was 007 which is a fuser issue. I found that
the fuser film and element were burnt. I replaced the parts and the
printer was printing normally!
