Scanner Error 30.03.45 in HP M525 DN Laserjet Monochrome Multi-Function Printer

Contributed by Haresh Karamchandani

We got an order from the Liberia Electricity Corporation after a successful competitive tender process to supply 7 pcs of HP M525DN MFP’s.

The printers were imported from source in the USA and we supplied them to the client. It was agreed in our proposal that we would supply and install the printers.

We fixed a date with the client and proceeded to go and install the machines and designated offices in their multi storied building.

We unpacked the printers one by one and got down to installing them. Six machines were installed with no problems and tested by the client. One was reading a Fatal Scanner Error Code 30.03.45 after we would start it up. The notification was: Restart the machine and if the error persists contact HP Tech Support.

We decided to bring back the machine to our Lab for further diagnostics.

The DC Board was switched to see if this was the problem but it still gave the same error. 

Then we suspected that the problem may have been caused due to damage to the scanner assembly and got down to getting a new scanner assembly from HP under the warranty arrangements. HP tech support said that before they send the replacement scanner they would like to do some troubleshooting with us.

We called up HP tech support and they asked us to do the following troubleshooting:

  1. Start the printer. 
  2. Hide the error message.
  3. Go into Administration>Reports>Configuration/Status pages>Configuration page>Print page
  4. The printer was able to print out the configuration page.
  5. Then the HP Technician advised that we download the Firmware from:>support>Enter product name which is M525dn>One match found, click on the match>Select Cross Operating System(BIOS, Firmware, Diagnostics etc)>Download Firmware>Download the 134.2MB firmware>After downloading the firmware, Extract the files and save on a blank USB stick> Insert the USB stick into the USB port, located on the left side of the screen panel>Click on Device Maintenance>USB Firmware Upgrade.
  6. Sit back, have a coffee, relax.
  7. The machine will automatically upgrade the firmware and it will restart 3-4 times during the process.
  8. Finally after the process is completed, the machine comes on without the error message!!
  9. The machine has been tested and it can print copy scan as usual.

We have packed the machine back into its box and will have it delivered and installed at the client site immediately.

Thanks to HP Tech Support!

NATC has several maintenance contracts with clients in the mining, NGO, UN and banking sectors. Each contract is tailored for a client's needs including Danish Refugee Council (DRC). Our contract entails regular visits to their offices in Harper which is the capital of Maryland Country in the eastern part of Liberia. 

See pictures of our most recent visit in the third week of May. 

En route!

We hitched a ride on a regular UN Helicopter flight to Harper 

Inside the heli

We managed to get some great photos of the coastline
as we lifted off and headed east. 

Since helicopters fly at a height of 10,000 - 15,000 feet, lower than fixed-wing aircraft,
one can get some great shots of the terrain.

We arrive and start working

But before we start work, we have to have lunch!

After lunch, we can get to work!

Business trip to Ivory Coast, Ghana and Nigeria

Our head of operations, Haresh, recently made a business trip to Ivory Coast, Ghana and Nigeria to source some goods for a battery bank supply order. 

These are some photographs from his trip, mostly in Abidjan. There's also a photo of his reunion with his secretary from 100 years when he used to live and work in Lagos, Nigeria.

HP M4345 Multi-Function Printer, Printing Blank Pages!

Contributed By Jonathon Barwon

We have a huge contract with a UN Organization to maintain and service about 91 printers, copiers, scanners.

During our last maintenance visit we routinely serviced a HP M4345 MFP and carried out a regular test print. The user signed off on our maintenance log and all was well.

About a week later we got an email from the client that the printer was printing blank pages and they started blaming us for this problem. They said that they had tried to replace the toner to no avail. I was dispatched by my Head of Operations to go and check out what may be the issue.

On arrival my first observation was that the client was using fake toners. I straight away condemned the toner and told the client that if we get a genuine toner from our stock the problem would be resolved. The client accepted and we sent for a Genuine HP toner.

To my utter shock and embarrassment, on insertion of the Genuine HP toner the machine rejected it and we got a message on the printer: “ Remove Orange tab”, this was already removed before the toner was inserted into the printer, and all of us were surprised and confused on what may be the problem. The client mocked me and said that your toner too is fake and that the printer was not able to recognize it!!!

We brought the printer to our lab and got down to diagnosing the problem.

We had some spare parts available and swapped the main PSU (Power Supply Unit), the High Voltage PSU, the scanner board, the DC controller and the formatter. We also swapped the transfer roller. 

All these ideas did not help at all.

On a thorough examination, my Head of Operations noticed that there is a spring on the left side of the printer that should make contact with the toner sensors. He suspected that this may be malfunctioning. He called up HP tech support in the USA and they advised that the problem may be due to a broken laser shutter flag.

I decided to go back to the client to inspect another similar printer to see if there is indeed any laser shutter flag in a working printer, and to also check the spring. And lo and behold, I noticed that the spring in the working printer was placed quite differently than the spring in our faulty printer. I quickly rushed back excitedly and placed the spring back correctly and carried out a test print.

Guess what? The printer is now working perfectly well. Imagine what one tiny spring can do? This spring was apparently dislodged when a user jammed in a toner cartridge. When dislodged it was right down below the white piece of plastic, whereas the actual position should be above the white plastic.

Networking Project at BIVAC

Contributed by Jonathan Barwon

NATC recently completed a networking job at the Bureau Veritas Inspection Valuation Assessment and Control (BIVAC) offices. 

What was our goal? Following the initial technical survey that was carried out by the Head of Operation Mr. Haresh Karamchandani and Head of IT Mr. Jonathan D. Barwon,  the goal of this networking job was to replace all damaged network cables and cable channels;  to make sure that all cables are well labeled and arranged in channel; and also creating new data points in some offices and departments. Our job was spread over a 3-floor building. 

The solution also included installation of a 9u server rack with a switch to give internet access to all users on the ground floor.

See the 'before' pictures. 



Implementation: We started the work on March 12, 2014 which was on a Wednesday. We were asked by the Administrator of BIVAC to work only on a weekends and holidays, reason was that they are very busy during the week days and cannot let go a day without work. 

Ground floor or first floor So, we started work from the ground flood in the data center or customer care center which is on the left side of the first floor. We setup a Cisco 24-port switch to connect all users on the ground flood to access the network. The 24-port Cisco switch is getting internet connection from a network cable coming from the Server room (IT Office). We created eight (8) new dual-port data points which is 16 data points in the customer care center and three (3) data points for the three (3) Receptionists' desktop. We also created five (5) dual-port data points which is ten (10) data points in the Program Department, which is on the right side of the first floor. All the network cables are connecting directly from the Server room. 

The Server Room is located on the third floor of the building.

We passed the cables from the top of the building as you can see in the picture below; the team is at work try to pass the network cable into PVC pipe from the top of the building or the third floor where the IT room or Server room is located.


The second floor of the building is hosted or been used by the Country Manager (CM), General Manager (GM) and the Secretary to the Country Manager (CM).

We set up an eight (8) ports Cisco switch in the secretary's office to give internet access to six (6) data points on the second floor. The Country Manager (CM)'s two (2) data points are getting internet access  from the Server Room. The total number of data points on the second floor is ten (10).

The third floor of the building is used by the IT Department/Server Room, HR Office, Finance Office and Maintenance Manager Office. Data points were installed as follows: two (2) data points in the Maintenance Manager's office; six (6) data points in the Finance Office;  two (2) data points in the HR Office; and four (4) data points in IT Room for the IT manager. All of the connections are from the 48 ports Cisco switch in the IT Room or server Room.

We also connected two (2) data points in the LAB Building. The cable is coming connecting from the 24-Port switch on the ground floor.

The job took 3 weeks to complete.

See a picture of neatly arranged cables in the server room.
