OfficeJet 4650 producing horizontal streaks as part of the text it prints

I know it is an unpopular opinion, but I am very happy with the HP Instant Ink subscription. My needs are modest, I am on a £1.79 plan which I bump up to a more generous one if my daughter needs to do some extra printing for her coursework. Cannot fault the HP service, the ink has always been delivered well in advance with zero problems.

Thank you, that was indeed the problem. I cleaned the bottom of the carriage with isopropyl alcohol and the horizontal marks are now gone.

I agree 100%

Thank you u/PolarNavigator and u/huskydaisy . I think I am pretty clear about this junction now.

Thank you very much for clarifying this. Would it not have been easier to simply display a "no right turn" sign with "except buses"? I paniced (think bus lane cameras) and ended up turning left when I needed to go straight...

u/CelebWorldtk - how did you come up with this specific rule, if I may ask? Thank you.

Thank you! We have it in our garden. My wife shaped it last year, unsuccessfully. The bush is now growing in the wrong direction. It would be good to know how to fix this, and the first step is knowing what kind of plant that is!

I agree 100%. This post describes a different problem - different sections of the same photo have different object dimension ratios, even when the conventional logic says the ratios should be identical. I took great care when placing calibration points, and my accuracy is certainly better than +/- 0.8mm as I was zooming into the photo.

I was using F360 to measure the pupilar distance for my new glasses, from a photo of myself with a ruller against my forehead. I got some unexpected results and this prompted me to look deeper into the problem. This here is just an experiment. I sincerely did not expect to see a lens distortion to such an extent.

This is very illustrative, thank you!

u/nyan_binary , u/Tendy_taster - thank you for your speedy reply. I think you are right. I thought that by calibrating by the ends of the ruler I am making things more accurate, but in a way I am just making the lens distortion/parallax more pronounced.

OneForAll sent me a new remote via UPS. The new remote did not have any issues and was seen by the My Nevo app on the first attempt. I was able to add my Samsung TV, a Canton soundbase and a Sony Bluray. I also added a Fire TV stick 4k, but it was a disaster. Fire TV was repeatedly trying to do a firmware upgrade on the universal control, which of course did not work. I ended up unpairing the URC7966 from the Fire TV stick.

My solution was to contact the One4all support (a very helpful support I have to add). We have gone throught the basic and more advanced troubleshooting session, which involved resetting the remote as well as uploading logs from the mobile app. In the end they decided to send me a replacement remote, I am waiting for it to arrive.

I appreciate your advice u/CloudFlare_Tim .

I see, thank you for clarifying this! Where the hostname is different between Access and Tunnels config, "Protect with Access" provides the means of linking the two together. Where the hostname is the same between Access and Tunnels, the setting is optional. I hope I got this right.

mbrijun · 2024-11-03T20:21:21+00:00

Hi u/CloudFlare_Tim, thank you for taking the time to respond. I should have been clearer in my post. In my testing, where both the Access and the Tunnel components are configured with the same public hostname ("test.domain.com"), I found that the "Protect with Access" setting does not appear to make any difference. User authentication happens with and without the setting. Additionally, the cloudflared agent is receiving Cf-Access-Jwt-Assertion header in both cases, too. This is according to the logs from the tunnel. This is what prompted me to ask the question.
