While installing a new maintenance kit on a printer I ran into the issue of resetting the maintenance count. Unfortunately, Lexmark seems to have hidden this functionality and even Google wasn’t able to bring up any results for me.
That being said, I was eventually able to figure out how to reset the counter and this post is an attempt to make finding this answer easier for myself and others in the future 🙂
If your x658de can be summarized with this image, you may want to order a new maintenance kit sooner rather than later…
To reset the maintenance counter after installing a maintenance kit in a Lexmark x658de printer, perform the following steps:
1. Power down the printer.
2. Hold 2 and 6 on the printer’s keypad.
3. Power on the printer.
4. You’ll see the progress indicator as per normal but will eventually end up in a configuration menu screen instead of the regular home screen.
5. Select the option to reset maintenance count.
6. Exit the config menu. The printer will restart back into the home screen.
It seems there are steps for other Lexmark printers however I couldn’t find this one no matter how much I looked.
After a long break I finally continued work on both of my Android apps offering new updates for both Price Compare and the full version of School Scheduler. I’ve also updated the download links for School Scheduler on this website. Please contact me if you run into issues downloading the update.
School Scheduler finally has widget support. It’s now possible to view your schedule for the current day as a widget on the home screen.
Price Compare has had a number of improvements and fixes made to it. The most noticeable one is a new recommendation system to give you a better idea of the price of an item is a good or poor deal in relation to existing items stored in the app.
I’ll continue to try and find time to work on and improve these apps in the coming future. I’ve also been digging into Unity a bit to see if I can come up with any game ideas that would be worth releasing 🙂
Stay tuned! And thank you for all of your support!
It took a bit longer than I had planned on but I’ve finally started pushing out the first updates to 1.3. The update has been pushed for Paid users that purchased the app via Google Play.
Version 1.3 includes the ability to cancel individual classes or mark an entire course off for one or more days. Additionally, there’s an option to take the entire day off school either for holidays, spring break or for any other reason.
I also found and fixed a sync bug that has affected a few users since I had introduced the feature of syncing to Google Calendar. If you had deleted an event from Google Calendar before turning off sync, this would not be updated correctly within the School Scheduler app. I added a check now so it can be deleted and thus re-added the next time sync functionality is enabled within the app.
I’ll be keeping an eye on any issues that come up as a result of the new version and will push out an update for free users as well as update the Amazon and SlideMe markets once the version is deemed stable.
It’s been a while since I’ve posted an update, so here’s a little info of what I’ve been up to in recent months.
After spending some time learning about web based vulnerabilities I’ve also started looking into operating system vulnerabilities and exploitation by analysing malicious software. It’s been a blast so far and I hope to make use of these skills in the future.
As a result of my research in this area, my Android apps have taken a bit of a back seat in recent months. That being said, over the Christmas holidays I started to push ahead and began working towards a new update for School Scheduler, as more and more students are installing the app with the winter semester starting. The next update to School Scheduler will include bug fixes and a new (well requested) feature – the ability to cancel classes or block out holidays within the semester.
While working on the feature I’ve identified a number of areas within the code base that requires re-factoring and in some cases a better implementation all together. As a result I’ll probably look at re-writing the app which will take some additional time, but should yield a much more positive result. I’d also like to improve sync abilities between devices, so I’ll have to put some thought into the best way of implementing that. So the update with holidays/cancellations will be released as 1.3 and the rewrite of the app will most likely arrive as a version 2.0.
With Black Friday in this US this weekend I’ve lowered the price for Price Compare and School Scheduler down to $1.00 each. If you’ve been using the free version of either app and are looking to upgrade now is the time to do so!
If you haven’t already checked out the apps I strongly encourage you to do so. Please feel free to send any feedback you have on how to improve the app. I’ve been taking notes and have implemented a number of suggested features over previous updates!
This sale will end Nov 26th. I hope Black Friday treats you well and have a good and enjoyable weekend!
I enjoy reading up on security issues and learning about the latest attack vectors in the wild. As a result, I’ve found penetration testing to be an enjoyable and often rewarding experience. Last month I started reading into pen-testing web applications (specifically php but it also covered other web languages) and I learnt quite a bit as a result. I’d highly recommend reading The Web Application Hacker’s Handbook as it goes into a great amount of detail of some of the most common web vulnerabilities and ways to go about finding them.
After some reading and practice, I took aim at several WordPress plugins to see how secure they really were. Within a couple of days I found a Remote File Inclusion vulnerability for Advanced Custom Fields, which made it possible to execute arbitrary code from a remote host. I found this vulnerability on Oct 17, 2012 and it has been fixed as of 3.5.2 of the plugin.
When I have some free time, I’d like to continue diving in on this pen-testing both to gain some credibility and experience in the security field and as a way of winding down and working on something different.
School Scheduler and School Scheduler – Lite has been upgraded to 1.25 on Google Play. An Amazon update will be done soon after any initial reported issues have been addressed.
The biggest change in this update is taking advantage of Tablet’s screen size and keeping the main screen in view while managing courses and tasks.
This update also gave me a chance to do some re-factoring while moving things from activities into fragments. I did a fair amount of internal testing to catch as many bugs as I could before releasing the update (there are also bug fixes for importing classes/tasks from the calendar) but please contact me via e-mail if you notice any issues after the update.
This update will make it easier to work on new features in the future. I’m hoping to do another update soon, as one of the features I’m looking forward to implementing is exclusion dates (so you can mark off holidays or cancelled classes). Stay tuned!
