Because of this, any USB-related problem (hub, long cable, weak power from the port, front-panel ports, damaged cable) can cause the carriage to start moving and then <strong>stop<\/strong>.<\/p>\n<p>The second common cause is <strong>dust and sticky movement<\/strong> on the guide rail, or a dirty <strong>encoder strip<\/strong> (the transparent strip with tiny markings that the scanner uses to detect the carriage position).<\/p>\n<hr \/>\n<h2>Typical symptoms and what they mean<\/h2>\n<ul>\n<li><strong>The carriage \/ light bar stops in the middle<\/strong> and then everything goes silent \u2014 often caused by USB power, dirt on the guide rail, or a dirty encoder strip.<\/li>\n<li><strong>The scanner hums, tries to move, but slips or fails<\/strong> \u2014 this may indicate stiff movement (dust \/ old lubricant) or insufficient power.<\/li>\n<li><strong>Scanning starts and freezes during the process<\/strong> \u2014 sometimes this is a driver \/ app issue, and sometimes the encoder strip is the problem.<\/li>\n<li><strong>You hear crackling \/ grinding \/ frequent clicking<\/strong> \u2014 the belt or gears may be involved (it is better not to make it worse).<\/li>\n<\/ul>\n<hr \/>\n<h2>What to do first (the most common fixes)<\/h2>\n<h3>Step 1. Connect the LiDE \u201cthe right way\u201d (this is critical)<\/h3>\n<ul>\n<li>Connect the scanner <strong>directly to the PC<\/strong>, without a USB hub and without extension cables.<\/li>\n<li>It is better to use a <strong>rear USB port<\/strong> on a desktop PC (these are usually more stable for power).<\/li>\n<li>If you use a laptop, try a <strong>different USB port<\/strong>.<\/li>\n<li>Use a different <strong>high-quality USB cable<\/strong> (shorter is better).<\/li>\n<\/ul>\n<p><strong>Why this matters:<\/strong> if the USB power is not sufficient, the carriage may stop halfway or fail to return to its \u201chome\u201d position.<\/p>\n<h3>Step 2. Perform a full power reset<\/h3>\n<ol>\n<li>Disconnect the USB cable from the scanner.<\/li>\n<li>Wait <strong>2\u20133 minutes<\/strong>.<\/li>\n<li>Reconnect the USB cable directly to the PC.<\/li>\n<li>Wait 10\u201320 seconds and try scanning again.<\/li>\n<\/ol>\n<h3>Step 3. Remove USB and system \u201cconflicts\u201d<\/h3>\n<ul>\n<li>Temporarily disconnect other \u201cheavy\u201d USB devices (external drives, webcams, Wi-Fi adapters).<\/li>\n<li>Restart the computer and try again.<\/li>\n<\/ul>\n<hr \/>\n<h2>If that did not help: careful cleaning (this often helps older LiDE models)<\/h2>\n<p><strong>Before you begin:<\/strong> disconnect the USB cable. Do not use water and do not pour any liquid inside.<\/p>\n<h3>What you will need<\/h3>\n<ul>\n<li>a microfiber cloth or cotton swabs;<\/li>\n<li><strong>isopropyl alcohol<\/strong> 90\u201399% (or an alcohol-based cleaner);<\/li>\n<li>a flashlight.<\/li>\n<\/ul>\n<h3>Step 4. Clean the guide rail (metal rod)<\/h3>\n<p>Inside the scanner there is a <strong>metal rod<\/strong> that the carriage moves along. Dust and sticky old lubricant interfere with movement, so the carriage may stop.<\/p>\n<ol>\n<li>Open the lid and shine a flashlight inside.<\/li>\n<li>Find the <strong>metal rod<\/strong> along the carriage path.<\/li>\n<li>Lightly moisten a cotton swab with alcohol (it should not drip).<\/li>\n<li><strong>Carefully wipe the rod<\/strong> along the accessible length.<\/li>\n<li>Let it dry for <strong>5\u201310 minutes<\/strong>, then reconnect USB and test it.<\/li>\n<\/ol>\n<h3>Step 5. Clean the encoder strip (transparent strip with markings)<\/h3>\n<p>The encoder strip is a <strong>transparent strip<\/strong> with very fine marks. If it is dirty, the scanner may \u201close\u201d the carriage position.<\/p>\n<ol>\n<li>Find the transparent strip along the carriage path.<\/li>\n<li>Use a cotton swab \/ microfiber cloth with a drop of alcohol.<\/li>\n<li><strong>Wipe the strip gently<\/strong> with no pressure.<\/li>\n<li>Let it dry for 1\u20132 minutes and test the scanner.<\/li>\n<\/ol>\n<p><strong>Important:<\/strong> do not pull the strip and do not move its mounts.<\/p>\n<h3>Can you move the carriage by hand?<\/h3>\n<p>Sometimes you can try to move the carriage <strong>very carefully<\/strong> by 1\u20132 cm (only with the USB disconnected). But if it does not move easily, <strong>do not force it<\/strong>. Using force can damage the mechanism.<\/p>\n<hr \/>\n<h2>Software side (relevant for Windows)<\/h2>\n<p>If the mechanics seem fine (the carriage returns to the home position), but scanning still freezes, the problem may be the driver or the app.<\/p>\n<ul>\n<li>Reinstall the Canon driver and Canon software (if you use it).<\/li>\n<li>Try scanning from another application.<\/li>\n<li>Test scanning on another computer \u2014 this is the easiest way to tell whether the issue is hardware or software.<\/li>\n<\/ul>\n<hr \/>\n<h2>When it is better to stop and contact service<\/h2>\n<ul>\n<li>You hear <strong>grinding, crackling, or repeated loud clicking<\/strong>.<\/li>\n<li>The carriage does not move at all and feels \u201ccompletely stuck.\u201d<\/li>\n<li>The scanner disconnects \/ reconnects by itself (as if the USB connection keeps dropping) even when connected directly.<\/li>\n<\/ul>\n<p>In these cases, the belt \/ gears may be worn out or there may be a serious jam \u2014 DIY actions can make it worse.<\/p>\n<hr \/>\n<h2>Quick checklist for LiDE<\/h2>\n<ul>\n<li>Connect it directly to the PC, without a hub, using a short cable.<\/li>\n<li>Try a different USB port (preferably a rear port).<\/li>\n<li>Do a full reset (disconnect USB for 2\u20133 minutes).<\/li>\n<li>Clean the guide rail (rod) and the encoder strip.<\/li>\n<li>If the carriage moves but scanning freezes \u2014 reinstall the driver \/ try another app.<\/li>\n<\/ul>\n<hr \/>\n<h2>FAQ: common questions about CanoScan LiDE<\/h2>\n<h3>1) Why does the LiDE scanner freeze on one computer, but work on another?<\/h3>\n<p>Most often because of USB power differences (different ports \/ controllers), the cable, a USB hub, or Windows drivers.<\/p>\n<h3>2) Can I connect LiDE through a USB hub?<\/h3>\n<p>Sometimes yes, but for diagnostics you should always test <strong>a direct connection<\/strong> first. Many hubs provide less power or unstable voltage.<\/p>\n<h3>3) What is better for cleaning \u2014 alcohol or glass cleaner?<\/h3>\n<p><strong>90\u201399% isopropyl alcohol<\/strong> is better. It evaporates quickly and usually leaves no residue.<\/p>\n<h3>4) I cleaned it, but now it is worse. Why?<\/h3>\n<p>Most often this happens because of too much liquid (it got inside), too much pressure on the encoder strip, or because the strip was shifted. Always clean with a <strong>slightly damp<\/strong> swab and no force.<\/p>\n<hr \/>\n<h2>Typical mistakes when cleaning a LiDE scanner<\/h2>\n<ul>\n<li><strong>Pouring liquid<\/strong> inside the scanner (you only need to slightly moisten the swab).<\/li>\n<li><strong>Pressing hard<\/strong> on the encoder strip or trying to stretch it.<\/li>\n<li><strong>Pulling the carriage by force<\/strong> if it is stuck.<\/li>\n<li>Using <strong>acetone \/ aggressive solvents<\/strong> or abrasives.<\/li>\n<li>Testing the scanner before everything is fully dry.<\/li>\n<\/ul>\n<div class=\"social-share-buttons\"><a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?u=https:\/\/drivernew.com\/?p=77587\" target=\"_blank\" rel=\"noopener\">Facebook<\/a><a href=\"https:\/\/twitter.com\/intent\/tweet?url=https:\/\/drivernew.com\/?p=77587&text=Canon+CanoScan+LiDE+won%E2%80%99t+scan+and+the+carriage+%E2%80%9Cfreezes%E2%80%9D%3A+how+to+fix+and+clean+the+scanner+yourself\" target=\"_blank\" rel=\"noopener\">Twitter<\/a><a href=\"https:\/\/www.linkedin.com\/shareArticle?url=https:\/\/drivernew.com\/?p=77587&title=Canon+CanoScan+LiDE+won%E2%80%99t+scan+and+the+carriage+%E2%80%9Cfreezes%E2%80%9D%3A+how+to+fix+and+clean+the+scanner+yourself\" target=\"_blank\" rel=\"noopener\">LinkedIn<\/a><a href=\"https:\/\/pinterest.com\/pin\/create\/button\/?url=https:\/\/drivernew.com\/?p=77587&description=Canon+CanoScan+LiDE+won%E2%80%99t+scan+and+the+carriage+%E2%80%9Cfreezes%E2%80%9D%3A+how+to+fix+and+clean+the+scanner+yourself\" target=\"_blank\" rel=\"noopener\">Pinterest<\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>Canon CanoScan LiDE scanners (LiDE 20\/25\/30\/35\/40\/50\/60\/70\/80\/90\/100\/110\/120\/200\/210\/220\/300\/400, etc.) often work for years without issues, but over time some typical symptoms can appear: the scanner \u201cbuzzes,\u201d the carriage (the strip of light under the glass) stops halfway, the device \u201cfreezes\u201d at startup,&hellip;<\/p>\n<p class=\"more-link-p\"><a class=\"more-link\" href=\"https:\/\/drivernew.com\/?p=77587\">Read more &rarr;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"no","_lmt_disable":"no","footnotes":""},"categories":[27],"tags":[],"class_list":["post-77587","post","type-post","status-publish","format-standard","hentry","category-canon"],"modified_by":"DriverNew","_links":{"self":[{"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/posts\/77587","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/drivernew.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=77587"}],"version-history":[{"count":1,"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/posts\/77587\/revisions"}],"predecessor-version":[{"id":77588,"href":"https:\/\/drivernew.com\/index.php?rest_route=\/wp\/v2\/posts\/77587\/revisions\/77588"}],"wp:attachment":[{"href":"https:\/\/drivernew.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=77587"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/drivernew.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=77587"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/drivernew.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=77587"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
