Paper jam in HP LaserJet 3050 series (3052)

This is difficult. Normally when a paper stuck / jam in LaserJet 3050 series (my case is 3052), we can open the printer lid, take out the toner cartridge and pull the paper out. Close the lid and can print again. 

 

In case, i cannot see any paper jam/stuck after take out the toner cartridge but i know it's jam inside there. I've tried to turn off the printer for one minute and turn on again. I can hear the warming up sound is different from usual but when i try to check to see any paper stuck inside there, i can't find any. The paper is hidden inside some where. BIG ISSUE.

Finally, i found something. I followed the instruction below and try to clean the paper path.


It's work. The paper successfully pull out by the printer.

For those who not understand what is all-in-one control panel, please refer to photo below


This save my time and money with no need to send to repair.

This is the paper that cause me a lots of trouble.

Mars power bank 3000 mAh review

Recently bought a external battery charger for my Samsung mobile phone called Mars Power Bank 3000 mAh.




Since the instruction or manual behind the box written in Chinese, i will share this in English so that more people can understand how it's work.




The description is rather brief as below:



  • Please read the instruction behind this box before using this.
  • This product suitable to use in most smart phone and digital camera.
  • Please recharge this product at least once if didn't use for a period of 3 months.
  • During the charging process, you can feel slight heat which is normal.  
  • Please make sure this product in dry condition. Please do not clear this product with chemical cleanser.



For: Fix for various mobile and devices
Capacity: 3000 mAh
Input: DC 5V -1000mAh (Max)
Output: DC 5V -1000 mAh (Max)

Mentioned in the box, this device support most of the mobile phone brand like Apple, Samsung, Nokia and etc. 




It's very flexible where user can change the adapter to suit the different needs.





Adapters that come with this external battery





For my case, i recharge this external charger with my USB adapter. 



How we know that it's fully charged? There is a LED light indicator. When you start to charge the power bank, the LED is in Red color. Once fully charged, it will turn to Blue. It will takes about 2-3 hours.




Once it's fully charge, you can use it to charge you smart phone and it should work like charm. It will takes 2-3 hours to get the handphone battery fully charge. I'm using Samsung Galaxy S2




Is it safe? Mentioned in the Box, it's certified by CE. I guess it's safe.

The virtual machine could not start - VMware Workstation

Hit error below when try to start windows 7 in my VMware workstation

The virtual machine could not start. Make sure VMware Workstation is installed correctly and you have rights to run the software and to access all directories it uses, including directories in which the software is installed, directories containing the virtual disk and configuration files, and directories for temporary files.


How to solve it?

Restart your computer or stop VMware services that is running and delete all of the .lck folders and also the .vmem file in the vm guest directory. Guest directory is where your install the virtual machine. For my case, i install my virtual machine in "C:\Documents and Settings\user\My Documents\My Virtual Machines\Windows 7 - Base"



Now i'm able to start my VM. Thanks to suggestion http://darktraining.com/vmware/66/

MYSQL Error 1053: The service did not respond to the start or control request in a timely fashion

I'm running mysql in windows server 2003 and was running well all the while. Today, my colleague execute some script and cause mysql hang. So, we have decided to restart the server. After restart the server, window service show that mysql in starting status after 20 minutes. So, i have decided to kill the process in task manager and start the service manually.

Then i hit error message  "Error 1053: The service did not respond to the start or control request in a timely fashion" and fail to start mysql. I've tried to restart windows server again but it doesn't work. I'm not sure what is the reason. What i decided to do is take out the database my colleague work with previous and try to restart mysql service again. Where is mysql data file store? The location can be found in my.ini file.In my case, my file is stored in "C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.1". I cut the paste the database out of the folder and restart mysql. It's work!!

Hope this experience can share with friend who hit the similar scenario. For friends who face the same error, maybe this link might helps http://support.microsoft.com/kb/886695

An error occurred with the POP3 mail server. Mail server mail.xxxx.com responded - Thunderbird 10

My email client Thunderbird 10 working 100% good before today but this morning when i try to retrieve emal from my mail server, i receive error message
"An error occurred with the POP3 mail server. Mail server mail.xxxx.com responded"





I'm very sure that my mail server working fine because i can download my email using my Sumsung Galaxy SII. There must be something wrong with my laptop.

Finally, i found out that the root cause come from the antivirus that i'm using. I'm using avast! antivirus free edition. There is a feature call Mail Shield which will scan inbound and outbound email. Once i disable this feature, it's working back to normal.

Hope this sharing helps.

Mysql very slow for certain schema

I have a database/schema name inventorysoftware and have a .net windows application running on this schema. The issue is, the application run very slow on this schema (like each click need to wait about 30 seconds). I have about 40 others schema running in my development machine with windows XP Pro.

I have tried to google around the issue but can't find any similar problem. One thing i need to mention here is i have about 15 schema with name inventorysoftware_ddmmyy where dd=day, mm=month, yy= year. You know, developer like to keep the backup schema for testing. After the application deployed to customer, i decided to clean my 15 schema with name inventorysoftware_ddmmyy .

After i have deleted the schema, my application move very fast. I found the root cause for the slowness. Lesson learn, don't use the schema starting with the same name. It will kill you.
